The structure of elephants large ears allows them to stay cool during hot temperatures. Inside of the elephant’s ears is small blood vessels that are close to the surface of the skin. When the elephant flaps its ears, it creates a breeze that cools down their blood supply. This can cool down their body temperature about three degrees Celsius.
The structure of the large ears helps the elephant to function by allowing it to stay cool in the hot savannah. Elephants must be able to cool themselves down in order to maintain homeostasis, which they need to be living. Without a way to cool down, the elephant could overheat and die because the summers in the savannah where they live can get up to 20-30 degrees Celsius.
