Answer:
Simple squamous epithelium found in lung alveoli have thin and flat cell vital for the function of gas exchange while Simple columnar epithelium found in intestines are elongated in shape to aid the absorption of materials.
Explanation:
Epithelial tissues are tissues composed of one or more layers of cells. They line the internal and external surfaces of organs in the body. This question is comparing the epithelial tissues found in the intestine and lung alveoli.
The SIMPLE COLUMNAR EPITHELIUM is lines the surfaces of the intestines while the SIMPLE SQUAMOUS EPITHELIUM lines the alveoli of the lungs. The major difference between these two types of epithelium is their shape. Since they are both simple, they are made up of one layer of cell.
-However, the simple columnar epithelium are elongated in shape i.e stretched length to aid absorption while the simple squamous are made up of relatively thin and flat cells that resembles scales.
