Match the eye structure with its primary function:

Pupil = Regulates the amount of light entering the eye. Iris = Controls the size of the pupil and provides eye color. Ciliary body = Produces aqueous humor and helps with focusing. Lacrimal gland = Secretes tears to moisten and cleanse the eye.

Match the chamber of the eye with its fluid content:

Anterior chamber = Aqueous humor Posterior chamber = Vitreous humor Lacrimal gland = Tears Ciliary body = Aqueous humor

Match the eye structure with its protective function:

Eyelashes = Trap foreign particles. Tears = Destroy bacteria with enzymes. Eyelid = Protects the eye from injury and excessive light by blinking. Cornea = Protects the eye by refracting light.

Match the eye condition with its description:

Presbyopia = Age-related decline in near vision. Ectropion = Eversion of the lower eyelid. Photoreceptor damage = Impairs light detection and visual signaling. Presbycusis = Age-related hearing loss. Signup and view all the answers

Match the structure with its role in vision:

Pupil = Controls light entry. Suspensory ligaments = Focuses light using the lens. Photoreceptors = Convert light into electrical signals. Ciliary body = Changes lens shape to accommodate vision. Signup and view all the answers

Pupil = Controls the amount of light entering the eye Ciliary Body = Helps with accommodation for near and far vision Iris = Regulates the size of the pupil Lacrimal Gland = Produces tears to moisten and cleanse the eye Signup and view all the answers

Match the following components of the eye with their respective locations:

Anterior Chamber = Between the lens and the cornea Posterior Chamber = Between the lens and the retina Photoreceptors = Located in the retina of the eye Suspensory Ligaments = Connected to the lens and ciliary body Signup and view all the answers

Match the protective structures of the eye with their specific functions:

Eyelashes = Trap foreign particles to prevent them from entering the eye Tears = Moisten, lubricate, and cleanse the eye's surface Aqueous Humor = Fills the anterior chamber providing nutrients Vitreous Humor = Fills the posterior chamber helping maintain its shape Signup and view all the answers

Match the following vision-related terms with their descriptions:

Photoreceptors = Specialized cells that detect light and convert it into electrical signals Presbyopia = Age-related decline in the ability to focus on near objects Ectropion = Eversion (outward turning) of the lower lid Presbycusis = Age-related hearing loss Signup and view all the answers

Match the following problems or impairments with their description:

Ectropion = Outward turning Eversion of the lower lid Tears = Contain an enzyme that helps destroy bacteria and prevent infections Aqueous Humor = Produced by the ciliary body Iris = Colored portion of the eye Signup and view all the answers

Pupil

Controls light entering the eye; the black circle in the center of the colored part.

Ciliary body

Part of the eye that produces aqueous humor and helps change the eye's shape for focusing.
