The two structures that make up the ciliary body are the ciliary muscle and the ciliary processes.
Step-by-step explanation:
The ciliary muscle changes the shape of the lens for near and far vision. The ciliary processes secrete aqueous humor to nourish the lens and cornea.The two structures that make up the ciliary body are the ciliary muscle and the ciliary processes.
The ciliary muscle is a smooth muscle that surrounds the lens of the eye. It contracts and relaxes to change the shape of the lens, allowing for near and far vision.
The ciliary processes are folds in the ciliary body that secrete aqueous humor, a fluid that helps nourish and maintain the shape of the lens and cornea.
