Aqueous humor formation and flow
Aqueous humor
A clear, watery fluid that fills the space between the cornea and iris (anterior cavity). Passes from the posterior chamber to the anterior chamber through the pupil.
Seventh step of the aqueous humor
A group of channels send the aqueous humor to the veins in the sclera.
How is aqueous humor formed?
Active secretion by epithelial cells of the ciliary body's ciliary processes. The epithelial cells of the ciliary body's ciliary processes controls the fluid's composition.
Aqueous humor function
Helps the cornea keep its rounded shape, supplies nutrition to the eye.
Fourth step of how the aqueous humor flows.
Is secreted into the posterior chamber at a rate of 1-2mL per minute. Leaves the anterior chamber at a rate of 1-2mL.
First step of how the aqueous humor flows
The aqueous humor moves in the anterior cavity. As a result, it provides a significant route for nutrient and waste transport. Also acts as a fluid cushion.
Fifth step of the aqueous humor
The fluid is filtered through a network of connective tissues. Is located close to the base of the iris.
Eighth step of the aqueous humor
The fluid is removed and recycled at the same pace with the rate of creation at the ciliary body's ciliary processes.
Third step of how the aqueous humor flows
The fluid's pressure stabilizes the retina's position by pressing the neural layer against the pigmented layer. Similar to air in a balloon.
Sixth step of the aqueous humor
The liquid moves into the scleral venous sinus.
Second step of how the aqueous humor flows
The pressure given by this fluid, helps to maintain the eye's shape. Occurs because this fluid is in the eyeball.
