Question

Shivering ________ heat production, returning body temperature toward the original value.

a) Decreases
b) Halts
c) Increases
d) Stabilizes

Answer 1

Shivering is an involuntary action that increases heat production to help the body maintain its core temperature and return to homeostasis when exposed to cold. It is controlled by the brain through hormonal and muscular responses that enhance metabolic activity.

Step-by-step explanation:

Shivering increases heat production, returning body temperature toward the original value. Therefore, the correct answer is c) Increases.

When the body is exposed to cold, various mechanisms are activated to maintain homeostasis, one of which is shivering. Shivering is an involuntary response that involves the rapid contraction and relaxation of muscles, generating heat to warm the body. This process consumes ATP (adenosine triphosphate) and increases metabolic activity, which leads to more heat production. The brain coordinates these responses by triggering hormonal changes that boost metabolism, such as the release of thyroid hormone and epinephrine (adrenaline)
