how are fish gills adapted for gas exchange

WebThe lungs contain lots of alveoli, and each one is microscopic. The alveoli are the sites of gas exchange. Oxygen in the air diffuses into the blood stream and carbon dioxide diffuses into the air. The alveoli are adapted to make the rate of gas exchange as fast as possible. The millions of alveoli mean that the lungs have a huge surface area. WebSolution. Alveoli in exchange of gases: The human airway is composed of the nose, throat, nasal cavity, pharynx, trachea, epiglottis, alveoli, bronchioles, bronchi, and lungs. A small sac called alveoli helps with gas exchange. Alveoli have thin walls and a close network of blood arteries to allow gas exchange between blood and air-filled alveoli.
