One, it helps regulate body temperature, regulate body temperature through excreting sweat, controlling blood flow. Through sweating and blood flow, the integumentary system helps regulate the temperature of the body. Two, it provides protection. A barrier to microbes, a barrier to UV radiation, to dehydration, protection from abrasions, and from chemicals. Third, the integumentary system provides sensation, pain, temperature, touch. It's the primary means through which those sensations come to us (those type of sensations). It also helps with excretion excreting sweat, water, or heat from the body. It helps with immunity. It produces antibodies and helps remove microbes by epidermal cells loss. As the cells are lost, the service microbes are taken with those cells that are removed from the body that way. It also provides a blood reservoir, a way to move blood to the tissues and organs in muscles as necessary. Finally, it serves as a source of vitamin D production through UV radiation exposure. The integumentary system's seven main functions, once again, are regulating body temperature, providing protection, providing sensation, pain, temperature, touch, excretion, certain types of immunity, helping our immune system, blood reservoir, and then the production of vitamin D.
