Quizplus · Accepted Answer

The transfer of heat from arteries that carry warm blood past veins that carry cooler blood is an example of countercurrent heat exchange. This process helps to maintain a constant body temperature in animals and is commonly seen in marine mammals, birds, and fish. Insulation, evaporative cooling, and behavioral thermoregulation are different mechanisms that animals use to regulate their body temperature but do not involve countercurrent heat exchange.
