Alveoli:


* the air sac that is surrounded with capillaries for gas exchange

* is the functional unit for gas exchange


Sweat Glands (Skin)


* water (98%), salts, and a small amount of urea diffuse from the blood into sweat glands

* excreted through the process of perspiration (sweating)

* main job of sweating is to maintain body temperature (cool down)
