How Does GCSE Biology Revision "Thermoregulation" (Triple) Work?

Thermoregulation is how your body keeps you at just the right temperature, like a cozy blanket on a chilly night.

Imagine your body is like a thermostat in your house. When it gets too hot, like when you're running around outside on a sunny day, your body sends out signals to cool you down. It’s like turning on the fan or opening the window, your body does this by making you sweat, and the sweat cools you off as it evaporates.

When it gets cold, your body acts like a heater. You might shiver, that’s your body trying to warm itself up by using extra energy, just like when you wrap yourself in a big, warm blanket.

Your skin has special sensors that tell your brain if you're too hot or too cold. If it's chilly, your blood vessels get smaller to keep your heat inside, kind of like closing the curtains on a cold day. If it’s hot, they open up so more cool blood can flow near your skin.

Your body is clever, it changes how it works depending on what’s happening around you, just like you change clothes when the weather changes! Thermoregulation is how your body keeps you at just the right temperature, like a cozy blanket on a chilly night.
