Differentiation Between Respiration and Breathing

Differentiation Between Respiration and Breathing Report: The differentiation between respiration and breathing and an explanation of the adaptation of the alveoli and their role in gas exchange. Introduction This report will explore the differences between respiration and breathing by defining their structures and functions and attaching a hand drawn diagram of the respiratory tract to refer to. The author will also give an explanation of how gasses are exchanged through the alveoli by providing a table explaining the composition of inhaled and exhaled air. A description of the adaptations of the alveoli will be provided to show how they maximise the effectiveness of gas exchange. A summary will then be drawn from the findings. Differences between respiration and breathing The Respiratory System (Appendix .1) The respiratory system consists of tissues and also organs that help with the process of breathing. The core parts of this important system are the airways, lungs, linked blood vessels, and also the muscles that allow breathing. Airways The airways are pipes that carry oxygen to the lungs. They also carry waste gas, such as carbon dioxide out of the lungs. The airways consists of; linked air passages in the nose, (called nasal cavities), the mouth, Larynx (voice box), the trachea (windpipe) and lastly tubes named bronchi or also known as bronchial tubes, and also their branches. Air moves into the body through the mouth and nose, which warms and also wets the air. (Dry cold air can irritate the lungs causing problems for asthma sufferers). The air then moves down the Larynx and through the trachea. The windpipe splits into two bronchial tubes, the ait moves through here and then enters the lungs (Remedy Health Media, 2015). A thin flap of tissue named the epiglottis, covers the windpipe when swallowing. This prevents both food and drink from entering the air passageways that lead to the lungs, if this failed to be successful an individual could die. With an exception of some parts of the nose and the mouth, all of the other airways have special hairs known as cilia that are coated with tacky/sticky mucus. These cilia trap foreign particles and germs that enter the airways when breathing in. These tiny, fine hairs then collect the particles up to the mouth or nose. From there, theyre swallowed, sneezed or coughed out. Nose hairs and mouth saliva also trap germs and particles. Lungs and Blood Vessels Remedy Health Media (2015), also suggest that linked blood vessels and also the lungs carry oxygen to the human body and also remove carbon dioxide. The lungs are situated on either side of the breastbone and fill the area of the chest cavity. The left hand lung is ever so slightly smaller than the right hand lung to allow room for the cardiac muscle (heart). In both lungs, the bronchi divide into thousands of thinner tubes known as bronchioles and these thin tubes end in bunches of tiny rounded air sacs known as alveoli. Each of the alveoli are covered with little blood vessels known as capillaries. The capillaries connect to a complex system of veins and arteries that transport blood through the whole body. The pulmonary artery including also its branches carry blood which is holding only carbon dioxide and no oxygen to the capillaries that surround the alveoli. Inside the alveoli, carbon dioxide transfers from the blood into the air. In conjunction with this, oxygen transfers from the air and into the blood within the capillaries. The blood which is now carrying the oxygen moves to the heart through the pulmonary vein and also its branches. The cardiac muscle pumps the blood holding the oxygen out to the body. The lungs are separated into five sections known as lobes. Some individuals have to have a diseased lung lobe removed, however they can still breathe sufficiently by using their remaining lung lobes. Muscles Used for Breathing Human Kinetics (2015), state that muscles situated near to the lungs help expand (loosen) and contract, (tighten) the lungs to allow breathing. These muscles comprise of the diaphragm, intercostal muscles, abdominal muscles and muscles in the neck and also collarbone area. The diaphragm is the main muscle for breathing and is dome-shaped and located beneath the lungs. It divides the chest cavity from the abdominal cavity. They also explain that the intercostal muscles are positioned between the ribs. They also play a huge part in helping with our breathing. Beneath the diaphragm are the abdominal muscles. They help with breathing out when we breathe fast (for example, during exercise). Muscles in the neck and also collarbone area help with inhalation when other muscles involved in breathing dont work as well as they should, or when lung disease impairs breathing capacity. Breathing Inhalation Hyper physics (2012), explain that during inhalation, the diaphragm contracts (tightens) and moves down which maximises the space in the chest, allowing room for the lungs to expand. The intercostal muscles situated in between the ribs also help to enlarge the chest. They contract to move the rib cage both up and out when inhaling. As the lungs capacity increases, air is drawn in through the mouth and nose. The air makes its way through the windpipe and enters the lungs. After making its way through the bronchial tubes, the air finally reaches and moves into the alveoli. Through the extremely thin walls of the alveoli, oxygen taken from the air moves to the capillaries. Haemoglobin, a red blood cell protein aids the movement of oxygen from the alveoli to the blood. In conjunction with this, carbon dioxide travels from the capillaries into the alveoli. The gas has travelled in the bloodstream from the right side of the heart through the pulmonary artery. Blood carrying oxygen from the lungs is carried through the capillaries to the pulmonary vein which delivers the oxygenated blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into surrounding tissues (Hyper physics, 2012). Exhalation During the act exhalation, the diaphragm relaxes and moves up and into the chest cavity. The intercostal muscles which sit between the ribs also relax to decrease the space available within the chest cavity. As this available space in the chest cavity reduces, air rich in carbon dioxide is forced out of the lungs and then windpipe, and lastly out of the mouth or nose (Boundless Biology, 2015). Exhalation requires no effort unless lung disease is apparent or physical activity is taking place. During physically activity, the stomach muscles contract and force the diaphragm against the lungs more than usual which rapidly pushes air out of the lungs (Boundless Biology, 2015). The adaptations of the alveoli and their role in gas exchange Gas exchange An exchange of gases takes place within the alveoli, between the gases inside the alveoli and the blood. Blood that arrives in the alveoli has a greater carbon dioxide concentration which is produced during  respiration  by the body’s cells. However, the air in the alveoli has a much smaller concentration of carbon dioxide, resulting in a concentration gradient  which allows carbon dioxide to  diffuse  out of the blood and into the alveolar air (Intel, 2014). Also according to Intel (2014), blood arriving in the alveoli has a lower oxygen concentration (as it has been used for respiration by the body’s cells), while the air in the alveoli has a higher oxygen concentration. Therefore, oxygen moves into the blood by diffusion and combines with the  haemoglobin  in red blood cells to form the combined oxyhaemoglobin. This table taken from BBC (2014), shows the differences (estimated figures) in the composition of inhaled and exhaled air. Adaptations of the alveoli According to ABPI (2015), to maximise the effectiveness of gas exchange, the alveoli have numerous adaptations such as, they are folded, providing a much greater  surface area  for gas exchange to occur. Also the walls of the alveoli are only one cell thick which makes the exchange surface very thin shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood  capillaries  which ensure a good blood supply. This is important as the blood is constantly taking oxygen away and bringing in more carbon dioxide, which helps to maintain the maximum concentration gradient between the blood and the air in the alveoli. Lastly each alveolus is  ventilated, removing waste carbon dioxide and replenishing oxygen levels in the alveolar air. This also helps to maintain the maximum concentration gradient between the blood and the air in the alveoli (ABPI, 2015). Summary This report has explored the differences between respiration and breathing by defining their structures and functions. The author has also give an explanation of how gasses are exchanged through the alveoli by providing a table explaining the composition of inhaled and exhaled air. A description of the adaptations of the alveoli has been provided to show how they maximise the effectiveness of gas exchange. Bibliography About.

Veitnam War :: War, History, Politics

  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Vietnam War   Ã‚  Ã‚  Ã‚  Ã‚   When most people hear the words Vietnam, what does it make them think about? The main answer most people come up with is death, or policing actions of the United States. The Vietnam War wasn’t about death it was about the French Colonial Rule of South Vietnam.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"The Vietnam War was the legacy of Frances failure to suppress nationalist forces in Indochina as it struggled to restore its colonial dominion after World War II.† This is the start of Vietnam War. This is also one way that America was brought into the conflict of Vietnam.   Ã‚  Ã‚  Ã‚  Ã‚  The war was further escalated by North Vietnam trying to go in South Vietnam and turn them into a communist nation. Then America was brought more deeply into Vietnam as a policing effort to stop communism. â€Å"Military leaders viewed the Vietnam War as the Chinese doctrine of revolutionary war in action, (using Chinese and Russian arms to boot.)†   Ã‚  Ã‚  Ã‚  Ã‚  The United States had a geopolitical aim, they were to try and contain the spread of communism. This is one of the main reasons for America to go to Vietnam, to help stop the spread of communism the â€Å"United States supported the anti-communist regime known as the Republic of Vietnam,† or South Vietnam. The United States was in Vietnam to stop the North Vietnam communism movement by means of the U.S. staring air raids in the country. â€Å" Despite the U.S. military aid, heavy bombing, the growing U.S. troop commitment, and some political stability in South Vietnam after the election, the two countries were still unable to defeat the Viet Cong and North Vietnam forces.

Costa Rican Dress

Costa Rican clothes are similar to most Central and South American countries. There clothes were developed by the Climate of Costa Rica. Costa Rica Clothing today is separated into two groups traditional cultural clothes and modern clothing. Costa Rican traditional dress is used for traditional practices. Most of the cultural dress has layers. This is because of the climate of Costa Rica. You never know when it is going to rain because of its varied climate. Traditional dress is only worn on special occasion such as when they dance. Both women and men have different style of traditional clothing. Usually the clothes are the colors of the Costa Rican flag which are red, blue , and white. Mens dress is very simple but elegant. Mens traditional costume usually have a few different things. The pants are a solid color which usually is blue or tan. They usually wear a white button down shirt. Then around the waist they wear a red cummerbund which is like a sash. Around the neck of the man they would wear a kerchief tied around it. Then on their head they would wear a â€Å"chonete† which is a traditional type of Costa Rican hat. A Chonete is like a straw cowboy hat. Usually men in Costa Rica will not really wear shorts on a day to day basis but only to the beach despite the tropical weather of Costa Rica. Today in the fields Men still wear the traditional dress. Women's traditional dress has a few important characteristics. The dresses are usually tailored in a special style. All traditional dresses have thick ruffles that start at the shoulders and go out all the way down the dress. The dresses have no sleeves to cover the arms. They are usually the colors red,blue,and yellow. Another type of Costa Rica dress has a long ruffled skirt. This is usually made in shinny colored fabric. A white shirt is usually worn and a red cummerbund connects the dress at the waist. To top off all these wonderful dresses a flower is usually placed in the ear of the women.

Sir Lancelot Du Lake Essays - Holy Grail, Knights Of The Round Table

Sir Lancelot Du Lake Essays - Holy Grail, Knights Of The Round Table Sir Lancelot Du Lake Sir Lancelot du Lake Sir Lancelot du Lake was quite possibly the bravest and most gallant knight in the world. His battles were pretty much lopsided, due to his extreme skill. He was King Arthur's best knight. He was very adventurous and prone to getting into trouble, which he always came out of without a scratch. Why was Lancelot honored so? In the last four paragraphs, I will try to explain this to my best ability. Why did I say he was Arthur's best knight? Sir Lancelot was sworn to protect Guenevere, King Arthur's wife. At no time at all was he ever over come, except by either treason or enchantment. His belief in himself was strong enough that he wouldn't let anyone but the king push him around. Those that tried to do the pushing usually wound up with their blood on Lancelot's sword. Another reason he was the best knight at the Table Round, was because he upheld the ideals of chivalry and the heroic tradition. He believed in being noble, and just. As I said, Lancelot was very adventurous, and never turned down an endeavor. While out one day, he took a nap, and woke to find his friend gone, and four queens looking upon him. This is one of the few times Lancelot did something against his will, and he did it only by enchantment. He was set free by King Bagdemagus' daughter, on a deal that he would help the King win the upcoming tournament. He helped win the tournament by killing alot of knights, or simply defeating them in battle. By doing this, he earned his freedom. There are many reason's why Lancelot was honored the way he was. Lancelot fought for King Arthur, til his banishment for his acts with the Queen. He remained loyal to Arthur, and came back, when Arthur was on his deathbed. He delievered Excaliber back to the lake from which it came, and conveyed a message of forgiveness and love to Guenevere, from Arthur. Lancelot was defeated in battle only by Arthur, and only once, for they only fought once. His name was known to everyone, as the best knight in all the land. Lancelot had proven himself worthy of his title of the bravest and most noble knight around, many times, and probably did, long after the stories had ended, if they are true. Lancelot has always been my favorite knight, since whatever year we did King Arthur in grade school. The topics I have gone over are as truthful as I can make them, and I hope they get me a good grade. As I hope the points I have expended upon further support my topic, I know that everyone knows Lancelot, wether they heard it from a cartoon, an English book, or a movie, and that everyone knows what a great and fearless knight he was.

Quotes from Metamorphosis by Franz Kafka

Quotes from Metamorphosis by Franz Kafka Metamorphosis is a famous novella by Franz Kafka. The work centers around a traveling salesman, Gregor Samsa who wakes up one morning to realize hes turned into a bug. The absurdist story was considered to be part of the Dada art movement. Metamorphosis Quotes When Gregor Samsa woke up one morning from unsettling dreams, he found himself changed in his bed into a monstrous vermin. He was lying on his back as hard as armor plate, and when he lifted his head a little, he saw his vaulted brown belly, sectioned by arch-shaped ribs, to whose dome the cover, about to slide off completely, could barely cling. His many legs, pitifully thin compared with the size of the rest of him, were waving helplessly before his eyes.- The Metamorphosis, Ch. 1 Why was only Gregor condemned to work for a firm where at the slightest omission they immediately suspected the worst? Were all employees louts without exception, wasnt there a single loyal, dedicated worker among them who, when he had not fully utilized a few hours of the morning for the firm, was driven half-mad by pangs of conscience and was actually unable to get out of bed? - The Metamorphosis, Ch. 1 And now he could see him, standing closest to the door, his hand pressed over his open mouth, slowly backing away as if repulsed by an invisible, unrelenting force. His mother - in spite of the managers presence she stood with her hair still unbraided from the night, sticking out in all directions - first looked at his father with her hands clasped, then took two steps towards Gregor, and sank down in the midst of her skirt spreading out around her, her face completely hidden on her breast. With a hostile expression, his father clenched his fist, as if to drive Gregor back into his room, then looked uncertainly around the living room, shielded his eyes with his hands, and sobbed with heaves of his powerful chest. - The Metamorphosis, Ch. 1 Those had been wonderful times, and they had never returned, at least not with the same glory, although later on Gregor earned enough money to meet the expenses of the entire family and actually did so. They had just gotten used to it, the family as well as Gregor, the money was received with thanks and given with pleasure. - The Metamorphosis, Ch. 2 Hardly she entered the room than she would run straight to the window without taking time to close the door - though she was usually so careful to spare everyone the sight of Gregors room - then tear open the casements with eager hands, almost as if she were suffocating, and remain for a little while at the window even in the coldest weather, breathing deeply. With this racing and crashing, she frightened Gregor twice a day; the whole time he cowered under the couch, and yet he knew very well that she would certainly have spared him this if only she had found it possible to stand being in a room with him with the window closed.- The Metamorphosis, Ch. 2 Into a room in which Gregor ruled the bare walls all alone, no human being beside Grete was ever likely to set foot.- The Metamorphosis, Ch. 2 Gregors serious wound, from which he suffered for over a month - the apple remained imbedded in his flesh as a visible souvenir since no one dared to remove it - seemed to have reminded even his father that Gregor was a member of the family, in spite of his present pathetic and repulsive shape, who could not be treated as an enemy; that on the contrary, it was the commandment of family duty to swallow their disgust and endure him, endure him and nothing more.- The Metamorphosis, Ch. 3 What the world demands of poor people they did to the utmost of their ability; his father brought breakfast for the minor officials at the bank, his mother sacrificed herself to the underwear of strangers, his sister ran back and forth behind the counter at the request of the customers; but for anything more than this they did not have the strength.- The Metamorphosis, Ch. 3 I wont pronounce the name of my brother in front of this monster, and so all I say is: we have to try and get rid of it. Weve done everything humanly possible to take care of it and to put up with it; I dont think anyone can blame us in the least.- The Metamorphosis, Ch. 3, pg. 51 Growing quieter and communicating almost unconsciously through glances, they thought that it would soon be time, too, to find her a good husband. And it was like a confirmation of their new dreams and good intentions when at the end of the ride their daughter got up first and stretched her young body.- The Metamorphosis, Ch. 3

Power, Desire, Difference Essay Example | Topics and Well Written Essays - 2500 words

Power, Desire, Difference - Essay Example The specific psychical concerns of the symbolic may have been played down in some feminist writing, political issues have been played down (and deeply confused with psychical ones) in recent critiques of essentialism. The thing is, the challenge to Lacan is often read as, or reduced to, the challenge to patriarchal structures of language and phallogocentrism, which of course in part it is. Lacan's theory also covers the psychical organization, the argument that the symbolic is the condition of sanity; it is not purely about the patriarchal order of language (Chodorow: 1998:167). It should become evident that this facet of Lacan's theory has also received attention in French difference feminisms, especially from Irigaray. Moreover, it is only when this aspect of Lacan's theory is taken into account that the British feminist defence of him makes any sense. The symbolic's patriarchal nature relies on the interlocking functions of the symbolic father, and the notorious phallus. Lacan says the symbolic father intervenes in the imaginary ties between mother and child (Withford: 1986). For Lacan the actual father matters infinitely less than his structural, symbolic position as an intervening third party. In the imagination, the father's place is similar to the occupied by language, in that language intervenes in the imaginary dyad as the symbolic words that rupture the threads of phantasy that hold lack at bay and the illusion of union in place. To borrow the vocabulary of mainstream psychoanalysis for a moment, this intervention is critical to the process of psychical differentiation, to the subject's differentiating itself from others; and this is one reason why sanity relies on the symbolic (Withford:1988). How changing the sex of either the intervening third party or the primary care-giver, or the actual father's social spot, would af fect the process of differentiation is another matter; but real changes in either parenting models or the social position of women and men must have consequences for the symbolic. The phallus is the mark of need, and diversity in general and sexual difference in particular. As the mark of need, it pertains to the fact that the subject is not complete unto itself. It is here that the symbolic father and phallus connect; the former breaks up the illusion of unity, the latter represent that break (Withford: 1986:7). As the mark of difference in general, the phallus is allied with the logos, with the principle that the identification of difference is the condition of logic and language alike. That is to say, thinking as such requires difference. This brings to a critical Lacanian claim that sexual difference is the crucial one in being able to speak, thus think; and, mutatis mutandis, that speaking is critical to sexual difference. The visual recognition of sexual difference is a channel connecting the heterogeneous experience of the feeling, sensing body to something that is strange to it: the differential structure of language; in turn, that language allows it n ame the difference. In short, Irigaray, like Mitchell, may have a clinical issue in mind: the idea that the phallus is represented by the penis implies, according
