Question

Quizplus · Accepted Answer

Dolphins use countercurrent heat exchange to conserve body heat. This mechanism allows for warm blood to exchange heat with cooler blood traveling in the opposite direction, thus conserving heat in the core of the body. Choice A is incorrect because concurrent heat exchange does not involve the exchange of heat between two different fluids or substances. Choice C is incorrect because thoracic muscles are primarily involved in the movement of the chest during breathing, and not in the regulation of body temperature. Choice D is incorrect because diet alone cannot effectively regulate body temperature in dolphins.
