The ears of the elephant has a great number of blood vessels that run through it. When the elephant flaps its ears, the blood that is passing through its ears get cooled and eventually the body temperature of the animal gets regulated. Since elephants in Africa live in the hot savannah, they have large ears that help the animal keep itself cool.
it flaps it's big ears back and forth to keep cool
increase of surface area promote transpiration = the evaporation of water by sun etc. flapping of ears can also cool down animal by creating current of air
Elephant ears have a very large surface area to volume ratio - with blood vessels spread out throughout. This means that the blood vessels are close to the surface, allowing for heat to radiate out. Elephants can also use their ears to fan themselves with - they are large so create a nice breeze.
The elephant uses his ears to cool his body in two ways. The actual movement of the ear produces small relief, but the excess surface area allows the blood to cool before returning to the major organs.
Elephants ears are both shade and fans, and help to keep elephants cool in hot environments.
p
wave them
flap them or spray water on there selfs
an elephant uses its ears to keep cool by flapping them around its head therefor keeping it cool
an elephant uses its ears to keep cool by flapping them around its head therefor keeping it cool
by fanning them and the body heat runs to the veins in the ears and is loft cooling the body down
flaps its ears

it flaps them
Heat is lost to environment from ears .
