d) lens
4. area of greatest visual acuity.
a) aqueous humor
b) retina
c) fovea centralis
d) lens

The correct answers are:

1. The sensory layer of the eye. B) Retina

2. The structure most responsible for focusing light rays that enter the eye. D) Lens

3. Helps maintain the intraocular pressure; located in the anterior part of the eye. A) Aqueous humor

4. Area of greatest visual acuity. C) Fovea centralis

Explanation:

1. The sensory layer of the eye.

The retina covers the inside of the eyeball. It is considered as the sensory organ of the eye, where the perceived images are projected, are processed in the form of a nerve impulse that leaves the optic nerve.

2. The structure most responsible for focusing light rays that enter the eye.

The lens are the transparent structure inside the eye that focuses light rays in the central part of the retina.

3. Helps maintain the intraocular pressure; located in the anterior part of the eye.

The aqueous humor, is a transparent aqueous fluid secreted by the ciliary body, this liquid derived from the blood plasma, distributes oxygen and nutrients to the upper part of the eye and eliminates residual products. The dynamics of production and elimination of aqueous humor is very important to keep intraocular pressure (IOP) within normal limits.

4. Area of greatest visual acuity.

The fovea, or also known fovea centralis, is the center of the visual field, it is a narrow area of the retina that only contains cones. Its function is to help us have a vision as clear as possible with all kinds of details and precision.

1. Retina. 2. Lens. 3. Aqueous humour. 4. Fovea Centralis

Explanation:

Lens/Cornea covers the iris, pupil and anterior chamber; it's the primary light focusing structure.

Retina contains photosensitive rods and cone cells.

Aqueous humor condoms eyes pressure

Fovea Centralis is morst active part of the eye

answer; i believe the correct answer is (anemia);
