Show Basal Heat Production The once accepted general law that basal heat production is determined deter-mined by the rate at which heat is lost cannot be valid. Possibly because be-cause of some activity of the ductless duct-less glands, most heat is generated when an animal least needs it A living animal is like an engine. It burns up food like fuel and converts con-verts it into muscular energy. Also, it stores up some fuel in the form of fat and tissue and draws on it in time of need. All this is called metabolism. The idling rate of the human engine, when it is doing nothing more than breathing easily is called the basal metabolic rate. |
