What Is Both All Over And In One Place?


Integumentary System

In humans, the integumentary system comprises the skin, hair, nails, and exocrine glands, acting to protect the body from various kinds of damage. The integumen­tary system is essential for maintaining thermo­regulation while providing a water or abrasion barrier from outside. Thermo­regulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different.

Exocrine glands produce and secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous.
