What are physiological mechanisms in endotherms?Show answer
When the body is too hot, endotherms:
What is negative feedback control?Show answer
Thermoregulation in endotherms follows the standard homeostatic loop: a receptor detects a change, the hypothalamus acts as the control centre, and effectors (blood vessels, sweat glands, muscles) produce a response that opposes the change. Because the response reverses the original change, it is negative feedback, the same model used for blood glucose and water balance.
