Question

Quizplus · Accepted Answer

The vertebrate diving response and torpor both involve bradycardia, peripheral vasoconstriction, decreased oxygen consumption, and reduced blood circulation to conserve energy and oxygen. However, a build-up of lactic acid in the blood is not characteristic of these states; it typically occurs under anaerobic conditions, which these adaptations aim to minimize.
