contract, causing attacks of shortness of breath).

Air entering the lungs fills the alveoli, where oxygen passes into the blood, binding to the hemoglobin of red blood cells. At the same time, carbon dioxide produced as a result of metabolic processes is released from the blood and enters the alveoli to be released from the body through exhalation.

The functioning of the respiratory system is controlled by a special part of the brain - the respiratory center. It regulates the frequency and depth of breathing depending on the body's needs for oxygen and excess carbon dioxide.

After all, the human respiratory system is an amazing example of a complex and sophisticated mechanism that provides vital functions to the body. Understanding its anatomy and how it works can help us better understand how to maintain our health and fight diseases of the respiratory system.
