Alveoli

Vedclass · Answer

(A) Residual volume $(RV)$ is the volume of air remaining in the lungs even after a forcible expiration. This air is primarily trapped within the $Alveoli$ because they are the terminal air sacs where gas exchange occurs and they do not collapse completely due to the presence of surfactant and the structural arrangement of the lungs. Therefore,the correct answer is $Alveoli$.
