How do mammals generate heat
WebApr 25, 2024 · As the warm-blooded animals generate their own heat the body ratio of weight to surface is also important. A larger body mass produces more warmth, so a large body surface is used to lose heat in … WebWarm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy.
