Answer 2

➢ Iris

The iris belongs to the middle layer of the eyeball. It is located at the forefront of the vascular membrane, in front of the ciliary body, that is, the part of the iris between the sclera (white part of the eyeball) and the pupil.

➢ Functions

Iris is a part of the eye structure. There is a circular opening in the center of the iris called the pupil . It is like an adjustable aperture in the camera . The pigment contained determines the color of the eye. When the light is stronger during the day, the pupil will become smaller, and only a small beam of light will penetrate the pupil and enter the eye; when entering a dark environment, the iris will shrink back, making the pupil larger and allowing more light to enter the eye Most eyes of vertebrates have irises. Because everyone's iris is different, it is also used for identification.
