🧠 SEO Description:

The alveolus (plural: alveoli) is a tiny air sac in the lungs where the exchange of gases — oxygen (O₂) and carbon dioxide (CO₂) — takes place.
Each lung contains about 300 to 400 million alveoli, forming a large surface area for efficient gas exchange.
The wall of each alveolus is extremely thin and made up of a single layer of epithelial cells.
It is surrounded by a network of capillaries, allowing oxygen to enter the blood and carbon dioxide to leave it.
Inside, there is a thin moist layer that helps gases dissolve easily, and elastic fibers around the alveoli help them expand and contract during breathing.
This video explains the structure, function, and importance of alveoli in the human respiratory system clearly and simply.
