Answer:
The alveoli are sacks coated on their inner wall by white and sticky liquid, they can be more than a millimeter in diameter and surface active agent. In them there is the exchange of gases between O2 and CO2.

The dermis regulates body temperature in an individual if the outer environment is too hot or cold, by sweat in a hot environment as it regulates the sweat glands.
