The major organs of the Integumentary System are the skin, hair, and nails.

Levels of integumentary system


The integumentary system has multiple roles in homeostasis, including protection, temperature regulation, sensory reception, biochemical synthesis, and absorption. All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the body.

Sweat is a part of homeostasis and when this layer doesn't exist you cannot excrete sweat. Therefore, you could not use this as a way to cool off. If there was no integumentary system or it failed rocks and other unwanted objects could get into your body which would cause illnesses.


The skin is one of the first defense mechanisms in your immune system. Tiny glands in the skin make oils that enhance the barrier function of the skin. Immune cells live in the skin and provide the first line of defense against infections. The integumentary system works with the digestive system to encourage the uptake of calcium from our diet. The integumentary system also works closely with the circulatory system and the surface capillaries through your body.
