The '''integumentary system''' is the set of organs forming the outermost layer of an animal's body. It comprises the [[skin]] and its appendages, which act as a physical barrier between the external environment and the internal environment that it serves to protect and maintain the body of the animal. Mainly it is the body's outer skin.

The integumentary system includes [[skin]], [[hair]], [[Scale (zoology)|scales]], [[feathers]], [[Hoof|hooves]], [[claw]]s, and [[Nail (anatomy)|nails]]. It has a variety of additional functions: it may serve to maintain water balance, protect the deeper tissues, excrete wastes, and regulate [[Core temperature|body temperature]], and is the attachment site for [[sensory receptor]]s which detect pain, sensation, pressure, and temperature.
