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

The correct flow of aqueous humor follows a specific pathway vital for maintaining intraocular pressure and nutrient supply to the avascular structures of the eye, such as the lens and cornea. The first stage of this process occurs at the ciliary body, where aqueous humor is produced. It then moves into the anterior chamber of the eye, the space between the cornea and the iris.

From the anterior chamber, the aqueous humor passes through the trabecular meshwork, a spongy tissue that helps to regulate the outflow of the fluid. The final step of this pathway is the canal of Schlemm, a circular channel located at the junction of the cornea and the sclera, where the aqueous humor ultimately drains into the bloodstream. This precise sequence is crucial for maintaining normal eye function and pressure.

Understanding this flow is essential for grasping how intraocular pressure is regulated and how disturbances in this path can lead to conditions such as glaucoma. The other choices presented do not accurately represent the pathway that aqueous humor takes, thereby highlighting the importance of recognizing the correct anatomical sequence.
