THE ORGAN OF THE HEARING

The ear is the organ of the hearing.

The sound enters into the ear and the neurons transmit the information into the brain.The brain returns the information to the ear to make you listen.Sometimes when you get older you stop listening
or you listen bad it is because the brain does not get good information that one part of your body sends .
