In zootomy, the integumentary system is often the largest organ system of an animal, comprising skin, hair, feathers, scales, nails, skin glands and their products (sweat, slime). It distinguishes, separates, protects, and informs the animal with regard to its surroundings. Small bodied invertebrates of aquatic or continually moist habitats respire at their outer layer (integument). This gas exchange system, where gasses simply diffuse into and out of the interstitial fluid, is called integumentary exchange.
In botany, the integument refers to the envelope of an ovule.
The name comes from the Latin integumentum, which means "to cover".
Components[edit | edit source]
Cutaneous glands include:
- Sudoriferous glands - or sweat glands
- Sebaceous glands - oil-producing glands

- Mammary glands - milk-producing glands located in the breasts

Dermatology is the branch of medicine dealing with the integumentary system. As skin is the most visible organ, skin appearance or symptoms provides important clues not only to skin diseases but also to disorders of other organs, such as the liver. Skin is also the most vulnerable organ system because of exposure to radiation, trauma, infection, and harmful chemicals.
