breathing
The process of breathing from the basic processes of the human body, it provides oxygen necessary for the body and get rid of the carbon dioxide resulting from biological processes, which is a threat to the human body, and the process of breathing in several stages, starting from the nose of the human and ends by the exploitation of oxygen within the energy processes that occur within the cells, Is breathing done? What are its stages? What are the members involved in the breathing process?
Respiratory organs
The respiratory system consists of several members, the most important of which are:
- the nose: The nose is the primary oxygen receptor through the inhalation process. It contains olfactory cells that smell and a mucous membrane that purifies oxygen from dirt and impurities. The capillaries and small hair in the nasal cavity are also purified.
- Pharynx: It is a joint channel between the respiratory system and the digestive system. The mouthpiece of the last mouth stops regulating the passage of air or food, and when the air passes, the tongue of the eagle moves to allow it to pass through the throat.
- throat: A portal connects the pharynx and the trachea. When speaking, the air passes through the throat, hitting the vocal cords within it until the sound produced by the person is formed.
- Bronchi: And contains a mucous membrane and cilia work to clean the air inside the body from the dirt and graduated outside, and the cylinder cylinder thin lined with fibers and muscles that control the size of the tramp based on the air inside and does not allow the lobe to expand too much, especially in the cough.
- Bronchitis: It is similar to the capillaries, which begin to branch out of the larynx in the form of tree branches that extend inside the lung and function as air transport into the lung.
- The lungs: Is located within the cavity of the thoracic column and vertebral column, and is located under the muscle of the diaphragm, and contains the capillaries and pulses of air, and the function of exchange of gases resulting from the processes of the body in which the exchange of oxygen with carbon dioxide by the alveoli, and installed on red blood cells to be transferred to All around the body by two gyro.
- Pulmonary capillaries: Are small filaments that spread heavily inside the lung and act to exchange gases between body and lung cells.
Factors Affecting the Breathing Process
The respiratory system, like other members of the body exposed to the dangers and factors that slow the performance of its functions, including:
- Air pollution from car and factory exhausts increases carbon dioxide in the air and, when inhaled, increases internal respiration, leading to fatigue and slow functioning of the lungs.
- Smoking and passive smoking: Smoking acts to block the airways, vesicles and endothelium of pulmonary capillaries by nicotine, reducing the efficiency of gas exchange.
- Bronchitis: which is caused by viral diseases, the most important of which is colds and flu.
- Do a great effort: we notice when doing arduous work to increase the rate of breathing and inhalation and exhalation.
