The integumentary system consists of the skin, hair, nails, and skin glands. The skin acts as a protective barrier and regulates temperature and moisture. It also contains sensory receptors. Common skin disorders include burns, eczema, psoriasis, and infections. The system can be described using medical terminology referring to the skin and its structures, functions, diseases, and treatments.
