The alveolus, which is the small air sac in the lungs where gas exchange occurs, is primarily covered by a thin layer of epithelial cells known as the alveolar epithelium. This epithelium consists mainly of type I and type II alveolar cells. Type I cells facilitate gas exchange, while type II cells produce surfactant, a substance that reduces surface tension and prevents the alveoli from collapsing. Additionally, the alveoli are surrounded by a network of capillaries, which facilitates the exchange of oxygen and carbon dioxide with the blood.

What is the adjective for alveolus?
The adjective for alveolus (singular) or alveoli (plural) is alveolar.
What part of the mammary gland produces milk?

How can the blockage of the alveolus be removed?
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.
What is the singular form of the word alveoli?
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).
Name the process involved in the passage of gas between the alveolus and the blood?
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.
What is a alveolus surrounded by?
Capillaries
