MEDICAL PHYSIOLOGY

Detailed explanation-1: -Pupil: The pupil is the opening at the center of the iris through which light passes. The iris adjusts the size of the pupil to control the amount of light that enters the eye.

Detailed explanation-2: -Pupil-The pupil is the black circle in the center of the eye, and its primary function is to monitor the amount of light that comes into the eye. When there is a lot of light, the pupil contracts to keep the light from overwhelming the eye.

Detailed explanation-3: -(PYOO-pul) The round opening in the center of the iris (the colored tissue that makes the “eye color” at the front of the eye). The pupil changes size to let light into the eye. It gets smaller in bright light and larger as the amount of light decreases.

Detailed explanation-4: -There’s an eye disorder known as aniridia which makes the eye appear to have “no iris.” In truth, there is a small ring of iris tissue, but it is so small and the pupil is so large that it can look like the eyes are completely black. It is due to a chromosome mutation.
