What are the two types of duct glands in the skin?

The two types of duct glands in the skin are sebaceous and sudoriferous glands. Sebaceous glands are responsible for the production of sebum, an oily substance that helps to lubricate the skin and hair, providing a protective barrier and preventing moisture loss. These glands are typically associated with hair follicles and play an important role in maintaining skin health.

Sudoriferous glands, also known as sweat glands, are involved in thermoregulation and excretion. There are two main types of sudoriferous glands: eccrine and apocrine. Eccrine glands are distributed throughout the body and help regulate body temperature through the secretion of sweat, while apocrine glands are located primarily in areas like the armpits and groin and are associated with scent.

The other options—vascular and lymphatic, dermal and epidermal, and follicular and connective—refer to different structures or systems within the body and do not pertain specifically to the types of duct glands found in the skin. Thus, identifying sebaceous and sudoriferous glands as the correct answer highlights their key functions and relevance to skin physiology.
