Quizplus · Accepted Answer

Structure E is the ciliary body, which is responsible for producing aqueous humor and adjusting the shape of the lens through contraction of the ciliary muscle and attachment through the ciliary zonule. The lacrimal sac (A) is not located within the eye, but rather is a part of the tear drainage system. The iris (B) is the colored part of the eye that controls the size of the pupil, and is located in front of the ciliary body. The ciliary zonule (C) is a ring of fibers that connects the ciliary body to the lens, while the ciliary muscle (D) is a smooth muscle located within the ciliary body that adjusts the tension on the ciliary zonule to change the shape of the lens.
