On the other hand, if the body needs to prevent the loss of excess heat, such as on a cool day, it will end up constricting the blood vessels of our skin. It does this by reacting differently to hot and cold conditions so that the inner body temperature remains more or less constant.Īnatomy of the skin: The skin is the largest organ of the integumentary system, made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments, and internal organs. The skin assists in homeostasis (keeping different aspects of the body constant, e.g., temperature). Human skin: This image details the parts of the integumentary system. This process is one aspect of homeostasis: a dynamic state of stability between an animal’s internal and external environment. The integumentary system functions in thermoregulation-the ability of an organism to keep its body temperature within certain boundaries-even when the surrounding temperature is very different. arrector pili: Any of the small muscles attached to hair follicles in mammals when the muscles contract they cause the hairs to stand on end.vasoconstriction: The constriction (narrowing) of a blood vessel.homeostasis: The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium such as the ability of warm-blooded animals to maintain a constant temperature.Evaporation: What happens when water crosses the skin via sweat glands and then dissipates into the air this process cools body temperature to within the body’s tolerance range. ![]()
