What is the respiratory system function?

The main function of the respiratory system is the replacement of gases such as oxygen and carbon dioxide in the lungs. Breathing or breathing allows this important function to take place. Air carrying oxygen enters the body during inhalation and air carrying carbon dioxide is excluded from the body by exhaling. Oxygen is a vital requirement of all cells to survive and perform many functions. Carbon dioxide is usually a waste product of processes inside the body and usually does not need cells.

All structures in the airways play an essential role in the system function. The upper airways, which include a nose, neck, voice box and trachea or trachea, are oxygen and carbon dioxide passages during the respiratory process. In the lower airways, composed of lungs, bronchi and alveolar bags, the gas exchange process takes place.

When the oxygen reaches the trachea, it travels to the two main bronchu, which is divided into the right lungs and the left lungs. Oxygen then continues to numerous bronchiols of each lungFinally, on millions of alveolar bags. Smaller blood vessels, called capillaries, are present on the surfaces of alveolar bags. Blood carrying carbon dioxide travels to the lungs through capillaries to replace the gas for oxygen. Blood transferring oxygen then goes to the heart to be delivered to other organs of the body.

The breathing process is governed by the central nervous system, diaphragm, lung and circulatory system. There is a respiratory center in the brain that regulates this process. The muscles in the chest, such as the membrane and the muscles between the ribs, help in the expansion and collapse of the lungs during every breath. After replacing gases in the lungs, oxygenated blood usually enters the circulatory system to achieve a part of the body.

Any interference in the components that regulate the breathing process can affect the function of the respiratory system. Diseases may include infections such as pneumonia, tuberculosis and bronchitis. Narrowing of the airwaysIt often makes breathing more difficult for many patients with asthma. Harmful substances such as tobacco smoke and radon gas can also achieve lungs if they are inhaled from the air. These substances can lead to the development of lung tumors and cancer, which often cause worsening of the respiratory system and other human body systems.
