GCSE Biology - How We Control Our Body Temperature #55

The video explains the regulation of internal body temperature, emphasizing the importance of maintaining a stable temperature of 37°C for optimal enzyme function. It describes the role of the hypothalamus and thermoregulatory sensors in detecting temperature changes and initiating responses to either warm up or cool down the body. Mechanisms such as vasoconstriction, shivering, vasodilation, and sweating are detailed as methods to conserve or release heat, ensuring homeostasis.

What happens to blood vessels when the body is too hot?

Explain how sweating helps in cooling the body down.
