Are humans ectothermic

Answer 1

Humans are ENDOtherms, NOT ectotherms. Endotherms include birds, mammals, and of course, humans. We maintain homeostasis [internal constancy] in all climates or temperatures. We are warm-blooded, but, unlike ectotherms, which lack internal temperature-regulating mechanisms and have to GO somewhere to either gain or lose heat, such as amphibians, for example, we humans, no matter the external temperature, maintain our constant [98.6] body temperature: we sweat when we're too hot so as to cool down. Behaviorally, we move to a cooler climate. When we're too cold, we usually shiver, which increases body heat. "Goosebumps" are another way the body attempts to hold in warmth, occurring when muscles contract.
