Elephants have massive ears to help regulate their body temperature. They have huge blood vessels in their ears. The blood vessels are large and quite visible on the backs of the elephant’s ears.
Flapping them creates air currents and exposes the ears' inner sides where large blood vessels increase heat loss during hot weather. The trunk is a prehensile elongation of its upper lip and nose. This highly sensitive organ is innervated primarily by the trigeminal nerve , and is thought to be manipulated by about 40,000–60,000 muscles.
