Which gland secretes sebum to lubricate the skin and hair?

Explanation:
Sebaceous glands secrete sebum, the oily substance that lubricates and protects the skin and hair. These glands are usually attached to hair follicles, releasing sebum into the follicle canal or onto the skin surface to keep hair soft and the skin moisturized. Sweat glands (sudoriferous glands) produce sweat for cooling and hydration, not sebum. Hair follicles are the structures that grow hair and may contain sebaceous glands, but they do not secrete sebum themselves. Skin pores are simply openings on the skin through which secretions exit, not glands. So the gland responsible for lubrication with sebum is the sebaceous gland.
