Capillaries
One alveolus is a singular, tiny air sac of the lung, surrounded by a network of capillaries, and through which oxygen and carbon dioxide are exchanged. A cluster of such air sacs are alveoli (plural of alveolus).
Each alveolus is surrounded by a network of capillaries, which are tiny blood vessels responsible for the exchange of oxygen and carbon dioxide with the surrounding tissues. This network allows efficient gas exchange to occur in the lungs.
The thin membranes are surrounded by blood vessels, enabling easy gas exchange.
The walls of the alveolus are very thin, allowing gases to easily diffuse across them. Additionally, the alveoli are surrounded by a dense network of capillaries, increasing the surface area available for gas exchange.
The adjective for alveolus (singular) or alveoli (plural) is alveolar.

Alveolar macrophage cells work to clear particles from the alveolus by phagocytosis. If this process is overcome by continued build up of particles then the alveolus becomes damaged. Once an alveolus is blocked there isn't much you can do.
Tiny air sacs surrounded by blood capillaries are called alveoli. They are the primary site of gas exchange in the lungs, where oxygen from the air is absorbed into the blood, and carbon dioxide is released from the blood to be exhaled. Each alveolus is surrounded by a network of capillaries, facilitating this crucial exchange between the respiratory and circulatory systems.
The process involved in the passage of gas between the alveolus and the blood is called gas exchange. This occurs through diffusion, where oxygen moves from the alveolus into the capillaries and carbon dioxide moves from the capillaries into the alveolus.
A small air sac at the tip of a bronchiole is called an alveolus. Alveoli are tiny, balloon-like structures in the lungs where the exchange of oxygen and carbon dioxide occurs. They are essential for efficient gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. Each alveolus is surrounded by a network of capillaries that facilitate this process.
