Homeostasis Project #4
Homeostasis is a tendency to maintain a constant internal equal balance in the properties of an organism in order to compensate for a changing external environment. When the body is too warm, too cold, and everything in between that requires a balance between certain parameters, homeostatic processes work to keep it stable. The body creates and excretes sweat to release heat. As water molecules evaporate from the skin, they take energy from the body with them when they leave. Evaporation requires energy because the forces of attraction between water molecules which need to be broken when water goes from a liquid to a gas. Although, sweating becomes less efficient in very humid external conditions because the body must
