Question

How are the alveoli designed to maximize the exchange of gases?

Answer 1

Alveoli in exchange of gases:

1. The human airway is composed of the nose, throat, nasal cavity, pharynx, trachea, epiglottis, alveoli, bronchioles, bronchi, and lungs.
2. A small sac called alveoli helps with gas exchange.
3. Alveoli have thin walls and a close network of blood arteries to allow gas exchange between blood and air-filled alveoli.
4. They have a balloon-like structure to maximize surface area in exchange for gas.
