Vasoconstriction and vasodilation play crucial roles in blood vessel responses to temperature changes.
Vasoconstriction and vasodilation are key processes in regulating blood vessel diameter and blood flow. In the experiment with the frog's foot, the cold water caused vasoconstriction, leading to a decrease in blood vessel diameter and blood flow rate. Conversely, the hot water at 35°C induced vasodilation, resulting in an increase in blood vessel diameter and blood flow rate.
