Question

Quizplus · Accepted Answer

Blood flow is the primary mechanism by which heat is transferred from an animal's core to its surface. The circulatory system carries warm blood from the core to the surface, where heat can be dissipated through radiation, convection, and evaporation.

Option A (muscle contraction) is not an efficient mechanism for heat transfer, as it generates more heat than it dissipates. Option C (nervous stimulation) is also not involved in heat transfer per se. Option D (conduction via interstitial fluid) and option E (convection via interstitial fluid) may contribute to heat transfer within tissues, but they are not the primary mechanism for heat exchange between the core and surface of an animal's body.
