It is secreted by the ciliary epithelium, a structure supporting the lens.
Formation of the aqueous humor. aqueous humor is secreted by the ciliary epithelium and circulates over the lens and through the pupil, i.e., it is found in the anterior and posterior chambers. similar in composition to protein-free plasma. normal volume is ~125 µL; pressure ~20 mm Hg. The aqueous humor is continually being produced by the ciliary body in the posterior chamber and drained out of the eye through the trabecular meshwork and canal of Schlemm in the anterior chamber. About 1 to 2.5 microliters of aqueous humor are formed and drained each minute. Aqueous flow from the posterior chamber to the anterior chamber. The aqueous humor supplies nutrients and oxygen to, and carries metabolic waste and carbon dioxide away from, the lens and the cornea. The aqueous humour is a transparent, gelatinous fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium, a structure supporting the lens. It is located in the anterior and posterior chambers of the eye, the space between the lens and the cornea. It is not to be confused with vitreous humour, which is contained within the larger cavity of the eye behind the lens. The drainage route for aqueous humour flow is first through the posterior chamber, then the narrow space between the posterior iris and the anterior lens (contributes to small resistance), through the pupil to enter the anterior chamber. aqueous humor the fluid produced in the eye and filling the spaces (anterior chamber and posterior chamber) in front of the lens and its attachments. It diffuses out of the eye into the blood and is regarded as the lymph of the eye, although its composition is different from that of the lymph in the rest of the body. see blood-aqueous barrier. aqueous flare. turbidity of the aqueous humor caused by increased protein levels and cells. aqueous humor. the fluid produced by the ciliary process in the eye and occupying the anterior and posterior chambers. 1 Aqueous humor dynamics • Secreted by ciliary epithelium lining the ciliary processes • Enters the posterior chamber. • 2  It then flows around the lens and through the pupil into the AC. • 3  There is convection flow of aqueous in the AC due to temperature gradiant.  Aqueous humor: In medicine, humor refers to a fluid (or semifluid) substance. Thus, the aqueous humor is the fluid normally present in the front and rear chambers of the eye. It is a clear, watery fluid that flows between and nourishes the lens and the cornea; it is secreted by the ciliary processes.  Aqueous humor flows from the ciliary body into the anterior chamber, out through a spongy tissue at the front of the eye called the trabecular meshwork and into a drainage canal (dark blue region next to the trabecular meshwork). Flow of Aqueous Humor. Most, but not all, forms of glaucoma are characterized by high eye (intraocular) pressure. Intraocular pressure remains normal when some of the fluid (aqueous humor) produced by the eye's ciliary body flows out freely (follow blue arrow). aqueous. watery; prepared with water. aqueous-blood barrier. see blood-aqueous barrier. aqueous flare. turbidity of the aqueous humor caused by increased protein levels and cells. aqueous humor. the fluid produced by the ciliary process in the eye and occupying the anterior and posterior chambers. Structure. The aqueous humour is filtrated from blood, modified in its composition, and secreted by the ciliary processes of the ciliary body in the posterior chamber. The volume of aqueous is about 0.2 microlitres, and it is entirely replaced every 1-2 hours. Aqueous humour flows around the crystalline lens and through the pupil into the anterior chamber. Most aqueous exits the eye through the passageways of the trabecular meshwork.
