The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.

Answer:
The correct order in which light passes through the structures of the eye is cornea → pupil → lens → vitreous humor
Explanation:
Light and images are the stimuli that must be perceived by the eye for the sense of vision to be produced. These stimuli must go through some ocular structures before reaching the retinal photoreceptors, passing to the optic nerve and being conducted to the brain.
The order of ocular structures that light passes through before reaching the retina is
- <em><u>Cornea</u></em><em>, the outermost layer of the eye that covers the iris.</em>
- <em><u>Pupil</u></em><em>, which corresponds to the opening in the iris that regulates the passage of light.</em>
- <em><u>Lens</u></em><em>, which is the transparent structure that is found in the anterior chamber of the eye and allows focusing.</em>
- <em>The </em><em><u>vitreous humor</u></em><em> is a substance with gel consistency that is behind the lens and separates it from the retina.</em>
The correct ocular function, with respect to vision, depends on the integrity of all structures through which light must pass before reaching the retina.
