The shape of the simple columnar epithelium cells are tall and narrow giving a column like appearance. the apical surfaces of the tissue face the lumen of organs while the basal side faces the basement membrane. the nuclei are located closer along the basal side of the cell.
A columnar epithelial cell looks like a column or a tall rectangle. A few epithelial layers are constructed from cells that are said to have a transitional shape. Transitional epithelial cells are epithelial cells specialized to change shape if they are stretched laterally.
Structure of the simple columnar epithelium The simple columnar epithelium is made up of a single layer of elongated cells which are always taller than they are wide and are directly attached to the basement membrane at the distal end. The nucleus is oval, large and is present at the base of the cell.
It can be identified by the number of layers and the shape of the upper layers. Complete answer: The columnar epithelial cells have four times their height to their width. They can be simple or unilayered and stratified or multi-layered. They are arranged like a pillar and are usually tall.
Simple columnar epithelium is located in the small intestine.
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.
Answer and Explanation: The answer is- a. dense microvilli. The simple columnar epithelium of the digestive tract is non-ciliated and contains dense microvilli.
The general characteristic of all epithelial tissue, including columnar is that the cells are closely packed together. Since they form the linings of organs and body cavities, they have at least one side that's not in contact with other cells. They lack blood vessels and obtain nourishment through diffusion.

The columnar epithelium is composed of epithelial cells that are column-shaped. The cell comprising the columnar epithelium is taller than it is wide. Its height is approximately four times its width. The nucleus in each cell is elongated and often found near the base.
A simple squamous epithelium is a simple epithelium made up of squamous epithelial cells. The squamous epithelial cells are characterized by being flat, possessing an oblong nucleus, and having a scale-like appearance. The cells are wider than they are tall and appear somewhat hexagonal when viewed from above.

The appearance of a large bubble with a rim of cytoplasm is typical of adipose cells, meaning the answer is B). White adipose cells, or fat cells, live true to their name and store fat.
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.
Characteristics of simple cuboidal epithelium? Single layer of cube-shaped cells, centrally located spherical nuclei.
