Question

How does the human body conserve heat? Select all that apply.
1 By decreasing muscle activity in the body
2 Through peripheral vasodilation in the body
3 Through peripheral vasoconstriction in body
4 By shunting blood to superficial body tissues
5 By shunting blood away from the skin surface

Answer 1

Answer:

3 Through peripheral vasoconstriction in body; 5 By shunting blood away from the skin surface

Explanation:

Controlling blood flow to the skin helps  maintain body temperature.

• Constriction of blood vessels reduces blood flow and  heat loss, while increased blood flow to the skin via vasodilation  increases heat loss and lowers body temperature.
• Muscle contraction uses energy and releases heat, so increasing the muscle activity (moving or shivering) will also help conserve heat.
