Explain the function and location of apocrine glands
|
Apocrine sweat glands are located in the axillae, breast areola, umbilical and anogenital areas, external auditory canals, and eyelids; they secrete thick milky substance of unknown composition that becomes odoriferous when altered by skin surface bacteria.

|
Explain the function and location of eccrine glands
|
Eccrine sweat glands are widely distributed over the body, except in a few areas, such as lips. Eccrine sweat is composed chiefly of water with various salts
|
|
|
What are the two types of sweat glands; what are their main functions, how do they differ?
|
Apocrine and Eccrine sweat glands’ function is to cool the body by evaporation, to excrete waste products through the pores of the skin, and to moisturize surface cells. Apocrine glands produce a thick, "milky" substance whereas eccrine glands produce a thin water like substance.
