Respiratory.. Provide the cells of the body with oxygen necessary for its activities. Burning food in the cells in the presence of oxygen



Provides respiratory cells of the body with oxygen necessary for its activities, and finesse of carbon dioxide - a product of the process of oxidative stress. Inhale air passes through the trachea and shins (Haptih narrower) to the lungs. Each lung include much of bronchioles poetic ending a countless number of alveoli (or alveoli) very thin membranes lining being through gas exchange of capillaries that surround Palansak. And working intercostal muscles (between the ribs) and diaphragm (under the lungs) to run the lungs Kalker (blower mourning), pulls the air outside of them to them and then you pay at regular intervals. 
It is known that the digested food is absorbed and transported into the blood, which will take it to all the cells of the body.
What happens to the food in the cells burn food in the cells in the presence of oxygen, generated by burning the energy needed for the body's activities and its vital functions, also generates carbon dioxide, and the combustion process these are called (breathing) food (sugars) + gas oxygen by breathing produces carbon dioxide + water + energy breathing importance to animal and plant life that any individual can survive for several days without food, but can not live without oxygen for several minutes.When you move your arms or legs, even when you close your eyes - for example - then you need to power and all living organisms (plants and animals) need energy, so vital functioning, ie they must breathe, so you get this energy. Are breathing in the plant through the stomata in the leaves, where it enters the atmosphere containing oxygen through them, to reach to all the cells of the plant, which binds oxygen with food, and launched the energy needed for vital operations of the plant. Respiratory: is the device that provides oxygen to the bodies of animals, and finesse of carbon dioxide. What respiratory components? And how does his job? Can answer the previous questions, through the following activities components respiratory Examine a model for the respiratory system to humans or plate to him, and you know its components, namely: (nose - pharynx - larynx - trachea - Divisions Alhoaúatan _ lungs) and contains the lungs on a wide range of bags Small thin walls, called alveolar, which earn the lungs totaling spongy, also surrounded by a bloody alveoli Bsairat earn pink lungs. There lungs and bronchi in the chest cavity, which ends of the bottom membrane muscular flexible called the diaphragm, separating diaphragm chest cavity from the abdominal cavity, and no thoracic cavity inside the rib cage, including addition of involvement mechanism breathing brought a plastic bottle, cut its base, and proved it a thin piece of rubber (balloon), and filling nozzle of the bottle stopper of rubber or cork implemented a plastic tube is installed on the end inside the bottle a small balloon, note here: small balloon inside the bottle is one of the lungs. Bottle is a rib cage. Piece balloon installed base represents the diaphragm. Drag a piece of rubber that represents the diaphragm down. Do you notice swelling balloon interior? Leave a free piece of rubber. Do you notice internal balloon deflation? Repeat the previous work several times to learn breathing mechanism and the processes of inhalation and exhalation role of the rib cage in the mechanism of breathing watched your chest, which rises during inspiration, which falls during exhalation.Former two activities: we can deduce the following: when the diaphragm muscle constrict fall to the bottom, and involvement rises to the top, Visa thoracic cavity, air enters the lungs, and this process is known as Balshahyq. Vbiq thoracic cavity and out of the air laden with carbon dioxide resulting from the combustion process food, and this process is known as exhale difference between inspiratory air Halzfer Take test Onpopta, containing the two quantities are equal of lime Alraiq water. Passed in one quantity of atmospheric air (representing air inhalation), by a blower for a certain period of time. Blow your mouth in the other tube exhaled air, by and for the same tube in any of Alonpoptan turbidity more lime water?Tube through which air sniffling) (the tube through which exhaled air () conclude that: no carbon dioxide in exhaled air quantity greater than those found in the air of inspiration. This can be explained as follows: Contains lungs on vesicles pneumatic thin walls, spread around the blood vessels, which allows the exchange of Ghazi "oxygen" and "carbon dioxide", And absorbs blood oxygen from the air inhalation, and get rid of "carbon dioxide" generated as a result of combustion food in the cells, and are expelled "carbon dioxide" outside the body in exhaled air need for oxygen at increased activity Put your hand on your chest, promised Views inhale or exhale, within one minute. Repeat this action after you by running for three minutes, for example, any more numerous cases? Before doing physical activity () after physical activity () from the previous activity conclude that: no carbon dioxide in exhaled air quantity greater than those found in the air of inspiration. This can be explained as follows: Contains lungs on vesicles pneumatic thin walls, spread around the blood vessels, which allows the exchange of gaseous oxygen and carbon dioxide, And absorbs blood oxygen from the air inhalation, and get rid of carbon dioxide generated from burning food in the cells and is expelled carbon dioxide outside the body in exhaled air. When a human physical activity; the body needs more energy, and this requires burning more food in the cells, and burning more food requires more oxygen, standing, number of times sniffling and physiology of the respiratory tract the nose: through nostrils enters air sniffling, and out exhaled air, and contains the nose on the bristles, purify air inhalation of dust also contains liquid mucous, moistens air inhalation before entering into the lungs, and contains the nose also membrane by many blood vessels, to heat air inhalation before entering into the lungs pharynx: allows Over inhale air from the nose to the throat throat: prevent the entry of food into the respiratory system, as there is at the top of the epiglottis, which closes the throat when swallowing food as in the figure. Trachea and divisions Alhoaúatan: allow the passage of air inhaled into the lungs and the passage of exhaled air to the outside of them, and there windpipe mucous membrane, and cilia help to expel any foreign objects may enter. Lungs: and there are alveoli and that is where gas exchange, where absorbs blood oxygen from the air inhalation, and get rid of carbon dioxide, which is expelled out of the body in the exhaled air to maintain respiratory health is nose safety valve for the respiratory system is subject to be air purification inspiration of dust, and moisture and air heating inspiration before entering into the lungs, so it's healthy breathing through your nose, and not through the mouth as some people do. And breathing human who engage in sports activities a greater quantity of air and lead to respiratory activation, renewal constantly Hoaúh, and I've created God Almighty respiratory fully integrated, bringing clean air to the lungs. But unfortunately, some of his behavior is not proper cause devastating respiratory by smoking or drug abuse, Smoking and drug abuse lead to inflammation of the respiratory tract, which makes it susceptible to chronic popular بالنزلات, and the accompanying cough and shortness of breath. Habitual smoking or drug use leads to addiction, and the consequent weak capacity for understanding, perception and loss of appetite, insomnia and nerve disorder and loss of balance and immune deficiency, respiratory with numerous diseases such as pneumonia, tuberculosis and influenza, a disease spread even among non-smokers or addicts by mixing or use tools patient prevention requirements of respiratory diseases away from patients and not to use their tools, and to avoid the spray, which scattered them during sneezing or coughing, and avoiding crowded places poorly ventilated when infection of the respiratory diseases should: early treatment and use of medication The recommended doctor full rest in bed, with good ventilation and eating good food no direct exposure to the cold. Not going out directly to the cold weather, after a shower with warm water away from smoking and smokers and avoid addiction and drug addicts.
