Accepted Answer

Sebaceous glands discharge an oily secretion called sebum into hair follicles. This helps to moisturize and protect both the hair and the skin. Ceruminous glands secrete earwax, apocrine sweat glands secrete a thicker type of sweat that is associated with body odor, merocrine sweat glands secrete a watery sweat to help cool the body, and mammary glands secrete milk for nursing mammals.
