Vedclass · Answer

(D) The correct sequence of air passage in the human respiratory system is as follows:$1$. Air enters through the external nostrils into the nasal cavity.$2$. From the nasal cavity, it passes into the pharynx, which is a common passage for food and air.$3$. From the pharynx, air enters the larynx (voice box) through the glottis.$4$. The larynx leads into the trachea (windpipe).$5$. The trachea divides into two primary bronchi (left and right).$6$. Each bronchus undergoes repeated divisions to form secondary and tertiary bronchi and bronchioles.$7$. Finally, the bronchioles terminate into thin-walled, vascularized bag-like structures called alveoli, where gas exchange occurs.Therefore, the correct sequence is: Nasal cavity $\rightarrow$ Pharynx $\rightarrow$ Larynx $\rightarrow$ Trachea $\rightarrow$ Bronchi $\rightarrow$ Bronchioles $\rightarrow$ Alveoli.

In man and mammals, air passes from outside into the lungs through which of the following sequences?
