What do the iris, ciliary body, and choroid collectively form?

Cornea
Uvea
Sclera
Retina

The correct answer is: Uvea

The iris, ciliary body, and choroid collectively form the uvea. The uvea is the middle layer of the eye and consists of the iris, ciliary body, and choroid. These structures play essential roles in controlling the amount of light entering the eye (iris), accommodating for near vision (ciliary body), and providing nutrition to the outer layers of the eye (choroid). The cornea is the transparent outermost layer of the eye, the sclera is the white protective layer covering most of the eyeball, and the retina is the innermost layer of the eye that contains light-sensitive cells for vision.
