Which of these allows mammals to maintain a regular body temperature?

Question

Quizplus · Accepted Answer

A four-chambered heart allows mammals to maintain a regular body temperature by providing efficient circulation of oxygen-rich blood to all organs and tissues, which is necessary to generate and conserve heat. Unlike reptiles, which are ectothermic and rely on their environment for heat regulation, mammals are endothermic and can regulate their own body temperature internally through metabolic processes. The four-chambered heart enables efficient oxygen uptake and delivery, which is crucial for metabolic heat production and maintenance of a constant body temperature. The other options, countercurrent gas exchange, an open circulatory system, and hemolymph and spiracles, are all traits of invertebrates and/or ectothermic animals and are not relevant to mammalian thermoregulation.
