oh yeah and the sweat one is pretty much wrong
according to wikipedia:
"Eccrine glands have three primary functions:
Thermoregulation: sweat cools the surface of the skin and reduces body temperature.
Excretion: eccrine sweat gland secretion can also provide a significant excretory route for water and electrolytes.
Protection: eccrine sweat gland secretion aids in preserving the skin's acid mantle, which helps protect the skin from colonization from bacteria and other pathogenic organisms."
so yeah waste removal is indeed a job of sweat
