Alveolar Air

Alveolar air is the air that fills the alveoli of the lungs and directly participates in gas exchange with the blood.

Alveoli are microscopic air sacs located at the ends of the bronchioles in the lungs. It is through the thin walls of the alveoli that gas exchange occurs between the inhaled air and the blood.

Oxygen from the inhaled air diffuses through the walls of the alveoli into the pulmonary capillaries, where it binds to the hemoglobin of red blood cells and is transported to the body tissues. At the same time, carbon dioxide from the blood diffuses in the opposite direction - from the capillaries to the alveoli, and is then exhaled.

Thus, alveolar air plays a critical role in gas exchange, providing oxygen and removing carbon dioxide. The efficiency of the respiratory function of the lungs directly depends on the composition and properties of this air.

Alveolar air is an important component of the respiratory system, which is involved in the gas exchange function of the body. In this article we will look at the main characteristics and properties of alveolar air, as well as its importance for human health.

Alveolar air is found in the human lungs and is a mixture of gases, primarily oxygen and nitrogen. It consists of 78% oxygen, 21% nitrogen and the remaining 1% other gases. A person breathes alveolar air, receiving oxygen and releasing carbon dioxide during breathing. Without alveolar gases a person dies
