Final answer:
Exocrine glands include sweat and oil glands, which secrete substances through ducts to the skin surface. Sweat glands come in two types: eccrine and apocrine, and they help with temperature regulation and body odor. Sebaceous glands produce sebum for skin and hair moisturization and antibacterial protection.
Step-by-step explanation:
Exocrine glands are a class of glands that include sweat and oil glands within the skin. These glands produce substances, such as sweat from sweat glands and sebum from sebaceous glands, that travel through small, tube-like structures called ducts. The exocrine glands can be simple, with a single duct, or complex, with branched ducts.
Sweat glands are responsible for producing the salty fluid called sweat, which emerges on the skin surface. There are two types of sweat glands: eccrine and apocrine glands. Eccrine glands are involved in regulating body temperature by releasing sweat onto the skin surface, while apocrine glands, which are usually found in the underarm and groin areas, become active during puberty and can be responsible for body odor.
Sebaceous glands produce an oily substance called sebum, which is secreted into hair follicles and eventually reaches the skin surface. The function of sebum is to waterproof and moisturize the hair and skin and to provide antibacterial protection against the colonization of microorganisms.
