alveoolne

Alveoolne refers to structures known as alveoli, which are tiny air sacs found in the lungs. These microscopic compartments are the primary site of gas exchange in the respiratory system. Each lung contains millions of alveoli, providing an enormous surface area for oxygen to pass from inhaled air into the bloodstream, and for carbon dioxide to move from the blood into the lungs to be exhaled. The walls of the alveoli are extremely thin, typically one cell thick, and are surrounded by a dense network of capillaries, facilitating efficient diffusion. This close proximity between air and blood is crucial for the vital process of respiration. Conditions affecting the alveoli, such as pneumonia or emphysema, can significantly impair lung function and gas exchange.
