Question

what will happen if the respiratory trach is not moist
​

Answer 1

Hello Friend...☺

There are two cases of this situation:

1) If the respiratory tract is not moist the dirt particles in the inhaled air will not be removed from air in the nasal cavities and reaches lungs and create problems to lungs.

2) The temperature of the inhaled air is brought close to that of the body for the smooth passage in the respiratory tract.

Answer 2

The respiratory surface needs moisture for maximum efficiency. Oxygen from the air dissolves in the water on the surface momentarily and this allows the oxygen more time to cross the alveoli membrane. If the surface dries out, gas exchange will happen at a very reduced rate since fast-moving gaseous oxygen molecules do not efficiently cross the alveoli membrane. The reduced gas exchange is mostly likely not enough to support blood oxygenation for vital functions
