B) simple cuboidal
C) simple squamous
D) simple columnar

Answers

Answer 1

Simple squamous epithelium lines the lungs, heart, blood vessels, and viscera. Option B is the correct response in this case.

What is simple squamous epithelia?

A single layer of cells that have been flattened and are organized in a continuous sheet makes up the simple squamous epithelium of the skin.

This kind of epithelium is found in places where rapid diffusion or filtration takes place, such as in the air sacs of the lungs, which is where oxygen and carbon dioxide are exchanged, and in the serous membranes that line the organs of the body, which are where they help to reduce friction. Both of these places are examples of places where this type of epithelium can be found.

In addition simple squamous epithelium is found lining the blood vessels, where it contributes to a reduction in the viscosity of the blood and protects the blood vessels from being harmed by the high pressure and flow of blood.
