Alveoli

Vedclass · Answer

(A) $1$. In humans, the lungs are the primary respiratory organs.$2$. Internally, the lungs contain numerous sac-like structures known as $alveoli$.$3$. The gaseous exchange occurs between the $alveoli$ and the surrounding pulmonary capillaries.$4$. Oxygen diffuses from the $alveoli$ into the blood, while carbon dioxide diffuses from the blood into the $alveoli$ due to partial pressure differences.$5$. Therefore, the site of gaseous exchange is the $alveoli$.

In human beings, where does the gaseous exchange take place?
