Besides providing a covering for the entire body surface, the skin performs many other functions, including protection against physical injury, sunlight, and microorganisms; prevention of loss of fluids from the internal environment; regulation of body temperature; continual reception of sensations from the environment, such as touch, temperature, and pain; and synthesis of vitamin D through the action of sunlight on the skin. Acid–base regulation occurs primarily in the lungs and kidneys. Metabolic rate is regulated by many hormones, not the skin.
