Question

Write the sequential order of organs for the passage of air in human respiratory
system.

Answer 1

Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi → Bronchioles → Alveoli or air sacs.

Answer 2

Answer:

The air enters the respiratory system through the nostrils and goes into the nasal chamber. The air then travels across the different parts of the pharynx o.r. nasopharynx, oropharynx and laryngopharynx, from here the air is then directed to the larynx. The larynx is present above the trachea which results in the air transferring to the trachea or the windpipe. The air travels through the bronchi from the trachea, and then to the bronchioles and then eventually reaches the alveoli for exchange of gases with blood.

Explanation:

The respiratory route of air in the respiratory tract is: Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi → Bronchioles → Alveoli or air sacs. Therefore, out of the given options, option D 'Nostrils —> pharynx —> larynx —> trachea —> alveoli' is the most appropriate option.
