Alveoli

Vedclass · Answer

(A) The $Alveoli$ are the primary sites of gas exchange in the lungs.These are thin-walled,bag-like structures surrounded by a dense network of blood capillaries.Oxygen diffuses from the $Alveoli$ into the blood,and carbon dioxide diffuses from the blood into the $Alveoli$ due to partial pressure gradients.Other structures like the $Trachea$ and $Bronchioles$ serve as conducting passages for air but do not participate in gas exchange.
