You go blind

Front 26

List the function of the parts of the eye.

Back 26

Light hits cornea.

Passes to pupil.

Lens focuses to retina.

Image goes to optic nerve.

Optic nerve send ls to brain.

Front 27

Back 27

Sound waves enter through eardrum and vibrate hammer then anvil then stirrup.

Stirrup send vibrations to cochlea and then are sent by cochlea to auditory nerve.

Semicircular canals control balance
