NEET PG DENTAL EXAM

Detailed explanation-1: -Air that is breathed directly into the lungs is not filtered. Breathing through the nose filters the air before it enters the body. Allergens, bacteria, viruses, etc. are filtered out of the body through the turbinates and other parts of the inside of the nose.

Detailed explanation-2: -Air is inhaled through the nostrils and warmed as it moves further into the nasal cavities. Scroll-shaped bones, the nasal conchae, protrude and form spaces through which the air passes. The conchae swirl the air around to allow the air time to humidify, warm, and be cleaned before it enters the lungs.
