Probably it's because it keeps the lungs moist so it doesn't dry out. Also, it's because if the air & temperature outside the body is so cold it hurts/you're breathing very hard/etc, you will definitely want warm air to warm up your body as much as possible. The body needs to stay at 98.6 degrees Fahrenheit to operate at maximum efficiency. Once your body goes above or below that, it stops working very well & behaves differently & oddly. The body heats up when you're sick to try to kill the infection, but it can't survive once it reaches somewhere between 100 & 106 or 108 degrees Fahrenheit; and the same when it becomes very very intolerably cold. So cold that your body's temperature starts to drop to a very dangerously low temperature and eventually shuts down. They describe the details in Perfect Disaster: Ice Storm.

What do gas exchange systems have in common?
The exchange surfaces are moist.
Why do gas exchange surfaces need to be moist?
The gases are to dissolve and diffuse through.
Why does the lungs having moist surfaces help improve gas exchange?
Surfactant
Which animals have moist skin?
Amphibians are known for having moist skin, as it helps with gas exchange through their skin. Some examples include frogs, toads, and salamanders.
What does gas exchange across a membrane require?
Gases must first dissolve in a fluid in order to diffuse across a membrane. All gas exchange systems require a moist environment.
How are leaves adapted for gas exchange?
they are connected to a densed network of blood vessels which keeps the oxygen moist
Why gas exchange surface like the alveoli in your lung are always moist?
In order for gas exchange to occur in the alveoli there must remain a constant supply of hemoglobin. Oxygen binds to hemoglobin and if these surfaces were dry then there wouldn't be any hemoglobin.
Which part of the human respiratory system is a moist membranous structure where gas exchange occurs?
alveolus (tiny air sacs arranged in clusters in the lungs, in which the exchange of oxygen and carbon dioxide takes place.)
Where is the respiratory surface?
A respiratory surface is located anywhere in an animal or human being where gas exchange occurs. A respiratory surface is located anywhere in an animal or human being where gas exchange occurs.
What two body organ systems are involved in gas exchange?
Amphibians use their lungs, and use their thin skin when its moist.
How does gas exchange take place?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.
Why multicellular organisms need special organs for exchange of gases between their body and their environment?
Our body is made up of prokaryotic cells. These cells are not in the contact with the environment. So the process of diffussion cant make any difference in exchange of gasses between the multicellular boy and environment.
