There is a dense network of blood vessels in the walls of the nasal cavity. This contributes to: a) warming the inhaled air b) gas exchange c) moving the inhaled air into the lungs d) distinguishing odors.

There is a dense network of blood vessels in the walls of the nasal cavity, this helps to warm the inhaled air. When it enters the nasal cavity, the air comes into contact with the vessels in which blood circulates at a constant temperature, thereby it warms up and passes into the lungs already warm. If cold air got into the lungs, this would lead to persistent inflammation with subsequent respiratory diseases, which in a complex advanced form can be fatal to humans.
