The respiratory system provides body cells with the oxygen necessary for their activities, and saves them from carbon dioxide - the product of their oxidation process. The air of inspiration passes through the trachea and the two sticks (narrow cubits) to the lungs. Each lung includes many capillaries that end up with innumerable vesicles lined with very thin membranes through which gases exchange from the capillaries surrounding the clones. The intercostal muscles (the ribs) and the diaphragm (under the lungs) activate the lungs like a bellows (bellows blower), pulling air into them and then pushing them out at regular intervals.
It is known that digested food is absorbed and transported to the blood, which carries it to all cells of the body.
What happens to food in cells The food burns in the cells in the presence of oxygen, and generates the combustion energy necessary to carry out the body activities and vital functions, and generates carbon dioxide, and the process of combustion called (breathing process) food (sugars) + oxygen gas by breathing Carbon dioxide + water + energy The importance of breathing for animal and plant life Anyone can live for several days without food, but can not live without oxygen for several minutes. When you move your arms or legs and even when you close your eyes - for example - you need energy and all the living things (plants and animals) need energy, to perform their vital functions, that is, they must breathe, to get this energy. Breathing takes place in the plant through the gaps in the leaves. The oxygen-containing air enters the plant's cells, where oxygen is combined with food, and the energy needed for the plant's vital processes is released.
Respiratory system: It is the organ that supplies oxygen to animals and saves them from carbon dioxide. What are the components of the respiratory system? How does he function? Respiratory components Test a model of the human respiratory system or plate. The components of the respiratory system are known as the nose, pharynx, larynx, trachea, lungs, and lungs. The lungs contain a wide range of bags Small, thin walls, called alveoli, which earn the lungs their spongy, and surrounded the alveoli with blood capillaries earn the lungs pink. The lungs and lungs are located in the thoracic cavity, which ends from the bottom of a flexible muscle membrane called the diaphragm. The diaphragm separates the chest cavity from the abdominal cavity, and the thoracic cavity is located inside the thoracic cavity, including the involvement of the breathing mechanism. Bring a plastic bottle and cut its base. A small piece of rubber (from a balloon), and plug the nozzle of the bottle with a rubber or cork plug from which a plastic tube is installed on the end of which inside the bottle a small balloon, note here: The small balloon inside the bottle represents one of the lungs. The bottle represents the rib cage. Piece balloon mounted on a base representing the diaphragm. Drag a piece of rubber, which represents the diaphragm down. Do you notice the bloating of the inner balloon? Leave the rubber piece free. Do you notice shrinkage of the inner balloon? Repeat the previous work several times to identify the mechanism of breathing and the process of inhalation and exhalation of the role of the thorax in the mechanism of breathing Watch your chest, which rises during the process of inspiration, which falls during the exhale. From the previous two activities, we conclude: When the diaphragm muscle contractes downward, the ribs rise up, the chest cavity expands, and the air enters the lungs. The chest cavity is narrowed and the air is emitted with CO2 produced by the food combustion process. This process is known as exhalation. The difference between inhalation air and exhale Take two test tubes containing two equal amounts of lime water. Pass in one of the air intake (representing the air of inspiration), by blower for a certain period of time. Exhaled air in your tube with the air of exhalation, by tube and for the same length in either tube, the lime water becomes more turbid? The tube through which the air passes through the air through which the exhalation air passes is deduced: the carbon dioxide in the exhalation air is greater than that in the air of inspiration. This can be explained as follows: The lungs contain thin walled vesicles, circulating around the blood vessels that allow the exchange of oxygen and carbon dioxide, the blood absorbs oxygen from the inhaling air, and releases the "carbon dioxide" generated by combustion Food in the cells, and "carbon dioxide" is expelled outside the body in the air exhaled the need for oxygen when increasing activity Put your hand on your chest, promise the number of times of inhalation or exhale, within one minute. Repeat this work after you have been running for three minutes, for example, which is more? Before performing physical activity after physical activity from the previous activity we conclude that: There is more carbon dioxide in the exhaled air than in the air of inhalation. It can be explained as follows: The lungs contain thin walled vesicles, circulating around the blood vessels, which allow the exchange of oxygen and carbon dioxide. The blood absorbs oxygen from the air of inhalation and excludes the carbon dioxide generated by food combustion in cells. Carbon dioxide Outside the body in exhaled air. When a person is physically active, his body needs more energy, and this requires more food to be burned in the cells. More food will require more oxygen, and the number of times will increase. Respiratory function The nose: Through the opening of the nose enters the air of inspiration, The nose contains bristles, purifies the air of inhalation from the dust and contains a liquid mucus, moisturizes the air of inhalation before entering the lungs, and the nose also contains a membrane with many blood vessels, to warm the air before inhalation into the lungs pharynx: allows The passage of air from the nose to the nose Carpentry.
Larynx: It prevents the intake of food into the respiratory system, as there is at the top of the tongue of the psalm, which closes the throat when swallowing food as the form. The trachea and the two airborne lobes allow the air of inhalation to pass through the lungs and the exhalation of the exhaled air. The trachea has a mucous membrane and cilia that help flush out any foreign bodies that may enter it.
The lungs are located in the alveoli where the gas is exchanged. The blood absorbs oxygen from the air of inhalation and removes the carbon dioxide, which is expelled outside the body in the exhaled air. Maintaining the health of the respiratory system The nose is the safety valve of the respiratory system. Of the dust, and moisturizes and warms the air of inhalation before entering the lungs, so breathe healthy through the nose, not by mouth as some people do. The person who carries out sports activities breathes a greater amount of air into the air, and this activates his respiratory system and renews his air continuously. God created the respiratory system fully and fully, so that the air reaches the lungs. But unfortunately, some of his improper behavior causes the destruction of his respiratory system through smoking or drug use. Smoking and drug use lead to respiratory inflammation, making him susceptible to chronic people's diarrhea and the accompanying cough and shortness of breath. The habit of smoking or drugs leads to addiction, and the consequent weakness of the ability to understand, perception and loss of appetite, insomnia, nervous disorder, loss of balance and immune deficiency, respiratory infection with many diseases such as pneumonia, tuberculosis and influenza, diseases spread even among non-smokers or Addicts through contact or use of patient tools Requirements for the prevention of respiratory diseases Distance from patients and not to use their tools, and avoid the spray that is scattered during sneezing or coughing, and away from crowded places poor ventilation when the disease of diseases of the device Respiratory: Early treatment and use of medicines recommended by the doctor should rest in bed, with good ventilation and eating good food not directly exposed to cold. Do not go out into the cold air directly, after showering with warm water away from smoking and smokers and avoid addiction and addicts.
