Endocrine glands

Verified step by step guidance

Step 1: Begin by identifying the primary function of each gland listed in the options. Sweat glands produce sweat to regulate body temperature, ceruminous glands produce earwax, mammary glands produce milk, salivary glands produce saliva, endocrine glands secrete hormones, and sebaceous glands produce oil.

Step 2: Focus on the specific function mentioned in the question: producing oil to lubricate the skin and hair. Recall that sebaceous glands are specialized glands located in the dermis layer of the skin and are associated with hair follicles.

Step 3: Understand the role of sebaceous glands. They secrete sebum, an oily substance that helps to keep the skin and hair moisturized, prevents dryness, and provides a protective barrier against microbial invasion.

Step 4: Compare the functions of the other glands listed in the options. None of the other glands (mammary, salivary, or endocrine) are involved in producing oil for skin and hair lubrication.

Step 5: Conclude that the correct answer is sebaceous glands, as they are the only glands responsible for producing oil to lubricate the skin and hair.
