Thermoregulation by skin
Webb13 aug. 2024 · The integumentary system consists of the skin, hair, nails, glands, and nerves. Its main function is to act as a barrier to protect the body from the outside world. … WebbAs the sweat evaporates from the skin surface into the surrounding air, it takes heat with it. The depth of respiration increases, and a person may breathe through an open mouth instead of through the nasal passageways. This increases heat loss from the lungs. Figure 1. Hypothalamus Controls Thermoregulation.
