Answer:
Vasoconstriction
Step-by-step explanation:
Vasoconstriction is a process in which blood vessels get narrowed or get constricted by the activities of small muscles present in the wall of the blood vessels. When blood vessels constrict, the flow of blood flow is slow down. This process is to conserve body heat. Thus, by vasoconstriction does not help the animal body to lower the increased body temperature. Whereas vasodilation, sweating, and panting lower body temperature if an animal’s body temperature exceeds the set point.
