Q

What role does the hypothalamus play in thermoregulation?

A

It acts as the body’s thermostat by receiving signals about body temperature and initiating responses to maintain it within a set range

Q

How does vasodilation help in thermoregulation?

A

Vasodilation increases blood flow to the skin surface, helping to dissipate heat and lower body temperature

Q

How does vasoconstriction help in thermoregulation?

A

Vasoconstriction reduces blood flow to the skin surface, helping to conserve heat and increase body temperature

Q

How do endothermic and ectothermic animals differ in thermoregulation?

A
  • Endothermic animals regulate their body temperature internally, mainly through metabolic processes
  • Ectothermic animals depend more on external environmental conditions to regulate their body temperature
