Stratified squamous epithelium​

Answer 1

Answer:

The type of epithelial tissue which consists of layers of flat cells is Squamous epithelium.

Explanation:

• Simple epithelial tissue refers to an epithelium with a free surface with a single layer of cells.

• The cells are compactly packed with a little intercellular matrix and are known to provide a covering or a lining for some parts of the body.

• Based on structural modifications of the cells, simple epithelial tissue is further classified into Squamous, cuboidal and columnar epithelium.

• Squamous epithelium is made up of a single layer of flattened or scale-like (Squama-scale) or spindle-shaped cells with irregular boundaries.

• The cells contain a centrally placed spherical nucleus and are closely fitted like the tiles on the floor with serrated edges which is why this epithelium is often known as pavement epithelium.

• Such epithelium is found in the walls of blood vessels and lymphatic vessels, in the lines of the body cavity and air sacs of lungs etc.

Hence Squamous epithelium is the correct answer.
