WebSome animals can use (and regulate) their metabolic heat production to maintain a relatively constant body temperature. These animals, called endotherms, include mammals, such as humans, as well as birds. Ectotherms, on the other hand, are animals that don't use metabolic heat production to maintain a constant body temperature. WebEndothermic animals mostly use internal heat production through metabolic active organs and tissues (liver, kidney, heart, brain, muscle) or specialized heat producing tissues like brown adipose tissue (BAT). In general, endotherms therefore have higher metabolic rates than ectotherms at a given body mass. ira thresholds 2022WebMar 15, 2024 · Birds and mammals can conserve body heat by fluffing up feathers or erecting their hairs and by reducing blood flow to the exterior surface and extremities.
