The thin, watery fluid that fills the space between the cornea and the iris is continually produced by the ciliary body. What is this fluid called?

This question hinges on knowing the fluids inside the eye and where they come from. The thin, watery fluid between the cornea and the iris is called the aqueous humor. It’s continually produced by the ciliary body and circulates from the posterior chamber through the pupil into the anterior chamber, nourishing the cornea and lens and helping to maintain intraocular pressure. In contrast, the vitreous humor is a gel that fills the space behind the lens between the lens and retina, the optic nerve is a nerve, and accommodation is the lens’s ability to focus. So the described fluid is the aqueous humor.
