Question

Give the structure of the nasal chamber.

Answer 1

Structure of nasal chamber:
The nasal chamber is divided into left and right chambers by nasal septum. Each chamber is divided into three regions -
(i) Vestibule: It is the anterior-most part of nasal chambers bearing hairs which filters the dust particles.
(ii) Respiratory region: It is rich in mucous glands and marked by nasal turbinates which trap the dust and humidify the air.
(iii) Olfactory chamber: It is lined by olfactory epithelium which senses the smell.
