Why is being moist important for gas exchange?

Answer 1

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.

Answer 2

We are mostly water. Dry air removes water from our body and dehydrates us causing death.

Answer 3

The lungs are moist so the alveoli do not dry up and so the lungs can still function properly. The air you breath helps to keep you lungs moist. :)

Answer 4

The respiratory tract is moist and which enableshould the efficient of diffusion across the alveomar membrane in the blood

Answer 5

The respiratory tract is moist to enable efficient diffusion of oxygen across the alveolar membrane into the blood.

Answer 6

When air is warmed and moistened, it helps keep the respiratory membranes in the lungs moist as well. This conditions increase the efficiency of gas exchange.

Answer 7

So you can breathe
