MICROANATOMY

Detailed explanation-1: -Simple epithelium. Simple epithelium is a single layer of cells with every cell in direct contact with the basement membrane that separates it from the underlying connective tissue.

Detailed explanation-2: -Epithelia composed of a single layer of cells is called simple epithelia; epithelial tissue composed of multiple layers is called stratified epithelia.

Detailed explanation-3: -A simple epithelium is an epithelial tissue made up of only one layer of epithelial cells. These cells are in direct contact with the basement membrane. And often the layer underneath the basement membrane is a connective tissue. The simple epithelium is primarily involved in absorption and filtration.

Detailed explanation-4: -Simple columnar epithelium is a single layer of columnar epithelial cells which are tall and slender with oval-shaped nuclei located in the basal region, attached to the basement membrane. In humans, simple columnar epithelium lines most organs of the digestive tract including the stomach, and intestines.
