GENERAL HISTOLOGY

Detailed explanation-1: -In humans, simple columnar epithelium lines most organs of the digestive tract including the stomach, and intestines. Simple columnar epithelium also lines the uterus.

Detailed explanation-2: -Types of epithelial cells in your body Simple columnar epithelium: This type of epithelium is often specialized for absorption and usually has apical cilia or microvilli. These cells line your stomach and intestines.

Detailed explanation-3: -The simple columnar epithelium is mainly involved in secretion, excretion, and absorption. The ciliated type can be found in the bronchi, uterine tubes, the uterus, and part of the spinal cord.

Detailed explanation-4: -Simple columnar epithelium consists of a single layer of cells that are taller than they are wide, with an oval nucleus usually located towards the basal region of the cell. As its name suggests, the cells of this epithelium have a colunm-like appearance in sections perpendicular to the basement membrane.

Detailed explanation-5: -The main function of simple columnar epithelial cells are protection. For example, the epithelium in the stomach and digestive tract provides an impermeable barrier against any bacteria that could be ingested but is permeable to any necessary ions. This function is especially important in the colon.
