The human nose undertakes the responsibility to warm 13
and moisturize the air we inhale. The mucus layer cov-
ering the interior surface of the nose releases water
vapor to moisture the air that enters. The large numbers
of capillaries immediately beneath the mucus layer also
warm the passing air, adapting it to the sensitive struc-
ture of the lungs. This mechanism resembles the air con-
ditioning system that regulates the levels of temperature
and humidity in buildings. The processes summarized
in outline here are in fact exceedingly complex.
