This is a left human ear.
This is what the anatomy of the human ear looks like, although the auditory canal is far too big in this image

The ear is the part of the body that lets people hear. Some animals, like people and most vertebrates, have two ears, but some animals do not hear through ears. Spiders have small hairs on their legs that they can hear with.

The ear works by directing sound to the inner ear. These vibrations are sent to the brain by a network of nerves.

The part of the ear that sticks out and can be seen is called the pinna.

Ears are also used in other ways. Elephants use their large ears to cool themselves when it is very hot.
