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.

State two ways in which endocrine glands and exocrine glands differ.
denis-greek [22]

Answer:

The two major differences lies in the function and support system.

Explanation:

The two major differences between an endocrine and an exocrine system are as follows –  

a) An endocrine system releases its produce (hormones) into the connective tissue i.e blood while the exocrine system releases hormones directly into the ducts so that it could reach the targeted tissue directly.  

For example – the Adrenal gland is an endocrine gland that secretes adrenaline directly into the blood. The salivary gland is an exocrine gland that releases its produce into the collecting duct leading to mouth. However, Pancreas is both endocrine and exocrine gland.

b) The endocrine system cannot work alone therefore it works in coordination with the nervous system to control actions and balance the body. However, the exocrine system works independently
