Question

Quizplus · Accepted Answer

Vasoconstriction is the narrowing of blood vessels in response to extreme cold, which reduces blood flow to the skin's surface and helps to conserve heat in the body's core. This is a common human response to extreme cold. Hypoxic ventilatory response is a response to low oxygen levels, not cold temperatures. Sickle cell disorder is a genetic blood disorder that affects the shape of red blood cells and is not related to the response to extreme cold. Vasodilation is the widening of blood vessels and is not a typical response to extreme cold.
