When Jay leaves his dark room and enters the bright hallway, his eyes begin to adjust to the increased amount of light. During this process, the size of Jay’s _________ will become smaller, allowing less light to pass through.​

Answer :

Answer:

The correct answer is: Pupil.

Explanation:

  • Light enters inside the side through a small opening in the iris of the eye which is called the Pupil.
  • The outer most part of the eye Cornea and the outer chamber aqueous humor are both transparent and allow light to refract through them.
  • The Iris, which a circular and thin comes next to the cornea and aqueous humor. It is reponsible for regulating the amount of light that can reach the retina by altering the pupil size.
  • The change in the size of the pupil is mediated by muscles in the iris.
  • There are two types of muscles, radial muscles and circular muscles.
  • In bright light, the radial muscles of the iris relax while the circular muscles contract. This decreases the pupil size allowing less light to pass into the retina.
  • In dim light,  radial muscles of the iris contract while the circular muscles relax. This increases the pupil size allowing more light to pass into the retina.
