What type of epithelial cell is flattened and thin?Multiple choice question.ColumnarPseudostratifiedSquamousCuboidal

Answer

The type of epithelial cell that is flattened and thin is Squamous epithelium.

Explanation: Squamous epithelial cells are characterized by their flat, scale-like appearance. They are arranged in a single layer (simple squamous epithelium) in certain areas of the body, such as the lining of blood vessels (endothelium) and the alveoli of the lungs. This thin structure facilitates efficient diffusion, filtration, and secretion.

In contrast:

• Columnar epithelial cells are taller and column-like, typically found in the gastrointestinal tract and are involved in secretion and absorption.
• Pseudostratified epithelium appears to be layered due to varying cell heights, but every cell contacts the basement membrane, often found in the respiratory tract.
• Cuboidal epithelial cells are cube-shaped and are commonly found in glandular tissues and kidney tubules, involved in secretion and absorption.

Thus, among the options provided, the correct answer is Squamous.
