Question

Which of the following events occurs during Phase B to raise body temperature to hypothalamus set point?

• A. Shivering
• B. Sweating
• C. Decrease in thermogenesis
• D. Cutaneous vasodilation

Hint:

Shivering is a protective mechanism activated by the body when it needs to increase its temperature, especially in cold conditions.

Answer 1

The Correct Option is A

In Phase B of temperature regulation, the body attempts to raise its temperature to the hypothalamus set point. Shivering is the key event that increases heat production through muscle activity. Shivering helps generate heat to warm the body. The other options (sweating, decrease in thermogenesis, and cutaneous vasodilation) are related to cooling the body, not raising its temperature.
