What role does vasoconstriction play in thermoregulation
Explanation:
In endotherms, warm blood from the body's core typically loses heat to the environment as it passes near the skin. Shrinking the diameter of blood vessels that supply the skin, a process known as vasoconstriction, reduces blood flow and helps retain heat.Thus, the blood returning to the heart has not lost much heat.
Answer:
Reduces blood flow and helps retain heat thus the blood returning to the heart has not lost much heat
