A girl has her eyes shut and is standing inside a brightly lit room. What happens to her pupils when she opens her eyes? Why?(1 point)
Responses
Her pupils grow because the muscles contract.
Her pupils grow because the muscles contract.
Her pupils grow because the muscles relax.
Her pupils grow because the muscles relax.
Her pupils shrink because the muscles contract.
Her pupils shrink because the muscles contract.
Her pupils shrink because the muscles relax
Her pupils shrink because the muscles contract. This is due to the pupillary reflex, which is controlled by the autonomic nervous system. When the eyes are exposed to bright light, the muscles in the iris contract, causing the pupils to constrict and reduce the amount of light entering the eyes.
