What is the primary function of sebaceous glands?

• A. To produce sweat
• B. To produce oil that lubricates the skin
• C. To provide sensation
• D. To regulate temperature

Answer: (B)

The primary function of sebaceous glands is to produce oil, also known as sebum, which serves to lubricate the skin and hair. Sebum plays a crucial role in maintaining skin hydration by preventing water loss, thereby acting as a barrier against external elements. This oil helps to keep the skin supple and can also have antimicrobial properties, contributing to skin health. While other glands in the integumentary system have distinct functions, such as sweat glands that primarily help with temperature regulation and sensation through nerve endings, it is the sebaceous glands that are specifically responsible for oil production. Thus, the answer that highlights the production of oil for lubrication captures the essential role of sebaceous glands within the broader context of skin health and function.
