Final answer:
The clear fluid known as aqueous humor fills the anterior chamber, the space between the cornea and iris/pupil of the eye.
Step-by-step explanation:
The space between the cornea and iris/pupil filled with a clear fluid known as aqueous humor is called the anterior chamber.
The eye is a complex organ divided into two main cavities: the anterior and the posterior. The anterior cavity is the one in front of the lens which includes the iris and is filled with aqueous humor, a watery fluid that helps to maintain intraocular pressure and provides nutrients to the eye. The posterior cavity, on the other hand, is located behind the lens and up to the retina, containing the vitreous humor, which is a more viscous fluid.
Not to be confused with the vitreous humor, the aqueous humor plays a critical role in eye health, circulating within the anterior chamber to deliver vital nutrients to the eye's tissues.
