MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Simple columnar epithelium consists of a single layer of cells that are taller than they are wide. This epithelium is often associated with absorption or secretion.

Detailed explanation-3: -Simple columnar epithelial cells are longer than they are wide. Characteristically, their nucleui are found at the base of the cell. The cells are connected by tight junctions. The cells receive nutrients through the basement membrane, which separates the cells from the capillary basal layer.

Detailed explanation-4: -Simple columnar epithelium consist of a single layer of cells that are taller than they are wide. This type of epithelia lines the small intestine where it absorbs nutrients from the lumen of the intestine. Simple columnar epithelia are also located in the stomach where it secretes acid, digestive enzymes and mucous.
