The oily secretion produced by sebaceous glands is called?

Explanation:
Sebaceous glands release an oily substance called sebum. This coating keeps hair and skin flexible, provides some waterproofing, and helps protect the surface from bacteria. The glands are usually connected to hair follicles, which is why sebum reaches the skin surface through the follicle opening. Keratin is a structural protein that forms parts of skin, hair, and nails, not a secretion. Melanin is the pigment that gives skin and hair their color. Sweat is a watery fluid produced by sweat glands to cool the body and remove waste. So the oily secretion produced by sebaceous glands is sebum.
