Answer
The aqueous humor is a filtrate that come s from the capillaries of the ciliary processes of the ciliary body; it accumulates in the posterior chamber of the anterior cavity and flows forward into the anterior chamber. From the anterior chamber it drains out of the eyeball through the scleral venous sinus into veins of the blood stream.
Work Step by Step
The anterior cavity of the eye comprises two cavities-- an anterior chamber, and a posterior chamber.
The anterior cavity lies between the cornea and the iris; the posterior chamber is behind the iris and in front of the zonular fibers and the lens. Both chambers of the anterior cavity contain aqueous humor.
This aqueous humor is a plasma filtrate that leaks from the blood vessels of ciliary processes of the ciliary body into the posterior chamber; thence this fluid flows forward between the iris and the lens,
passes through the pupil and enters the anterior chamber.
The volume of the aqueous humor in the anterior chamber is usually about 240ul. It is being constantly produced and must find a route of exit. From the anterior chamber the aqueous humor drains into the scleral venous sinus; thence it flows into the blood stream. The aqueous humor is responsible for most of the intraocular pressure.
