Question

Mention the syructural details of alveoli.​

Answer 1

Answer:

Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they’re microscopic, alveoli are the workhorses of your respiratory system.

You have about 480 million alveoli, located at the end of bronchial tubes. When you breathe in, the alveoli expand to take in oxygen. When you breathe out, the alveoli shrink to expel carbon dioxide.

Answer 2

Answer:

Alveoli are tiny balloon shaped structures and are the smallest passageway in the respiratory system. The alveoli are very thin, allowing the relatively easy passage of oxygen and carbon dioxide (CO2) between the alveoli and blood vessels called capillaries.
