THERMOREGULATION Flashcards
THERMOREGULATION
Humans produce heat in a variety of way:
- the endocrine system releases hormones to speed up our metabolism, causing heat to be released from these chemical reactions
-muscles contract rapidly (shivering) to produce heat
- the conversion of fat cells also produces heat.
Scenario - During cellular metabolism, our body creates heat and is sometimes can be too high > Thermoregulation:
Example- Running on a hot day.
- As you exercise, your body’s cellular metabolism increases, leading to higher heat production. If your body temperature starts to rise too much, your thermoregulation kicks in. You start to secret sweat to make your body cool down, and your blood vessels near the surface of your skin may dilate, allowing more blood to flow and releasing heat, they help regulate the body temperature and prevent it from getting too high.
