What is the primary function of sebaceous (oil) glands?

• A. To produce sweat
• B. To secrete sebum
• C. To regulate temperature
• D. To absorb nutrients

Answer: (B)

The primary function of sebaceous glands is to secrete sebum, which is an oily substance that helps to lubricate and protect the skin and hair. Sebum plays a crucial role in maintaining skin hydration and preventing it from becoming dry and flaky. Additionally, it has antibacterial properties that help protect the skin from infections. The secretion of sebum is particularly important in keeping hair shiny and reducing water loss from the skin, contributing to the overall health of both skin and hair. The other functions listed in the choices involve different types of glands and mechanisms in the body. The production of sweat is primarily carried out by sweat glands, which are responsible for thermoregulation and cooling the body through evaporation. Temperature regulation involves various physiological processes, including perspiration and blood flow, which are not directly related to the function of sebaceous glands. Absorbing nutrients is a function more commonly associated with the digestive system and not with the skin's sebaceous glands.
