Question

The epithelium capable of ultrafiltration is

• A. Squamous epithelium
• B. Cuboidal epithelium
• C. Columnar epithelium
• D. Compound epithelium

Answer 1

The correct option is A

Squamous epithelium

The correct option is A:

Explanation of the correct option:

1. Squamous epithelium is made up of thin, flat, disc-like polygonal cells.
2. Its function is protection from injuries, filtration, and diffusion.
3. Because they are very thin and flat in structure their function is filtration and diffusion of substances.
4. Found in alveoli of the lungs, basement membrane of the Bowman's capsule in the kidney.

Explanation of the incorrect option:

Option B:

1. The cuboidal epithelium consists of a square or cuboidal cells.
2. Present mainly on the tubular parts of the nephron and ducts of tubes.
3. Its main function is secretion and absorption.

Option C:

1. The columnar epithelium consists of elongated cells with elongated nuclei.
2. Its main function is absorption and secretion.
3. Present on the hollow inner surface of bronchioles and fallopian tubules.

Option D:

1. The compound epithelium is made up of many layers of cells.
2. Its main function is absorption, secretion, and protection.

Final Answer: Hence the epithelium capable of ultrafiltration is Squamous epithelium.
