Question

human eye part its structure and function

Answer 1

To understand how the eye sees, it helps to know the eye structures and functions:

Cornea: Light enters through the cornea, the transparent outer covering of the eye.

Iris and Pupil: Light passes through the cornea and aqueous humor through an opening called the pupil.

Function

The eye receives oxygen through the aqueous. Its function is to nourish the cornea, iris, and lens by carrying nutrients, it removes waste products excreted from the lens, and maintain intraocular pressure and thus maintains the shape of the eye. This gives the eye its shape.
