WebFeb 2, 2011 · 109943. Heat is continuously generated in the human body by metabolic processes and exchanged with the environment and among internal organs by conduction, convection, evaporation and radiation. Transport of heat by the circulatory system makes heat transfer in the body — or bioheat transfer — a specific branch of this general science. WebThere are three ways heat can be moved: convection, basically the heat moves because the object itself moves. conduction, the most intuitive one: when two objects touch, heat is transfered from the hotter to the colder. radiation, which always happen, is simply the natural emission of some electromagnetic waves, which takes energy, i.e. heat. great clips southtown
