Explain how the ears of a human control balance.

Human ear is not only responsible for hearing by also control balance.

Human ear has  three sections the outer; middle; and inner ear.

The outer ear consist of pinna and ear lobe, middle ear consist of  three tiny bones the malleus, incus and stapes, and inner ear contains cochlea and the vestibular system.

The inner ear carry vestibular system which consist of  three semicircular canals, saccule and utricle, responsible for maintaining balance.

The outer ear collects sound waves from outside and guide it to middle ear, and the middle ear changes the sound waves into vibrations and pass it to inner ear. the inner ear utilizes vibrations and send it to nerve impulses. The semicircular canals in the inner ear contains hair cells and  fluid and hair cells.  When anyone moves their head the fluid in semicircular canals moves along. the motion is then detected by hair cells, which are then send nerve impulses to the brain and functions in maintaining balance.
