WebEndotherms use their circulatory systems to help maintain body temperature. Vasodilation brings more blood and heat to the body surface, facilitating radiation and evaporative heat loss, which helps to cool the body. Vasoconstriction reduces blood flow in peripheral blood vessels, forcing blood toward the core and the vital organs found there ... WebBeing an endotherm means that your body can adapt to environmental changes in temperature to promote your survival. While mammals are endothermic species, most reptiles, amphibians, and insects are ectotherms. An ectothermic organism is unable to adapt to extreme changes in temperature due to its poor regulation of body temperature.
