Question

how does nasal chamber help in the process of breathing.

Answer 1

The process of taking air into the lungs is inspiration, or inhalation, and theprocess of breathing it out is expiration, or exhalation. ... Air pressure in the chest cavity and lungs is reduced, and because gas flows from high pressure to low, air from the environment flows through the nose or mouth into the lungs.

Answer 2

While we are breathing air passes through the nasal cavity/chamber to the lungs.

While passing through the nasal cavity the air gets purified i.e walls of nasal cavity have hair which prevent dust and bacteria to enter our lungs with the air.
