The word “integumentary” is an adjective that means “relating to the skin or other outer covering of an animal or plant.” It is pronounced with the stress on the third syllable, “in-TEG-u-men-ta-ry.” The word is derived from the Latin word “integumentum,” which means “covering.” The integumentary system is the organ system that protects the body from the external environment. It includes the skin, hair, nails, and sweat glands.
The integumentary system is important for a number of reasons. It provides a physical barrier between the body and the external environment, protecting it from harmful substances and microorganisms. It also helps to regulate body temperature, prevents water loss, and produces vitamin D. The integumentary system is also involved in sensation, communication, and thermoregulation.
