What is the primary role of sebaceous glands?

The primary role of sebaceous glands is to secrete oil, known as sebum, which plays a crucial role in lubricating both the skin and hair. This oil helps to maintain moisture in the skin, preventing dryness and contributing to the overall health of the skin’s surface. Sebum also has protective properties, as it can help to form a barrier against bacteria and other pathogens, reducing the risk of infections. Additionally, the lubrication provided by sebum helps to keep hair healthy and shiny, enhancing its appearance and manageability.

Other options highlight different glandular functions—sweat glands regulate temperature through sweat production, structures like hair follicles receive support from connective tissues rather than glands, and digestive enzymes are produced in other glands or organs, such as the salivary glands and pancreas. The specific function of sebaceous glands centers solely on oil production, making it distinct from the roles of the other glands mentioned.
