Which of the following is the correct direction for aqueous humor flow?

The flow of aqueous humor is a critical process in maintaining intraocular pressure and overall eye health. The correct direction for aqueous humor flow starts at the ciliary body, where it is produced. From the ciliary body, aqueous humor moves into the anterior chamber, which is the space between the cornea and the iris.

After filling the anterior chamber, the aqueous humor then passes through the trabecular meshwork, a spongy tissue that regulates the outflow of this fluid. Finally, it drains into the Canal of Schlemm, where it can ultimately enter the bloodstream. This sequence ensures that the aqueous humor is properly circulated and prevents the buildup of pressure within the eye.

Understanding this flow is important, particularly in the context of conditions such as glaucoma, where the drainage of aqueous humor is impaired, leading to increased intraocular pressure. Recognizing the correct pathway aids in comprehending how fluid dynamics contribute to ocular health and vision.
