Simple columnar epithelium is a type of epithelial tissue that is specialized for absorption and secretion. It is typically found lining the digestive tract where it helps in the absorption of nutrients. The columnar shape of the cells allows for efficient transport of molecules across the tissue.
The jejunum is lined with simple columnar epithelium. This type of epithelium is specialized for absorption and secretion, making it well suited for the functions of this part of the small intestine.
Simple ciliated columnar epithelium has cilia that help move substances across the cell surface, whereas non-ciliated columnar epithelium lacks cilia. Non-ciliated columnar epithelium is involved in secretion and absorption, whereas ciliated columnar epithelium is mainly found in areas where the movement of mucus or particles is important, such as the respiratory tract.
Simple squamous epithilium
A ciliated simple columnar epithelium helps to move particles or mucus along the surface of the tissue. The cilia on the cells beat in a coordinated manner to create a directional flow. This type of epithelium is found in areas like the respiratory tract and the fallopian tubes.
simple squamous epithelium
The intestinal epithelium, which covers the small and large intestine, is simple columnar and nonciliated. It lines most of the organs of the digestive tract.
The function of the gallbladder is to store bile produced by the liver
Simple = One layer Columnar = tall (column like) cells Epithelium = Lining, covering, and glandular tissue Simple columnar epithelium = A single layer of tall cell tissue

Simple columnar is more resistant to being torn apart because of its elongated, column-like structure. Simple columnar epithelium is thicker than simple squamous. Simple squamous is also a single layer of cells, but its cells are flattened. This makes it thinner and much more prone to being torn to the thicker simple columnar epithelium.
Pseudostratified columnar epithelium is a single layer of cells that appear to be layered due to varying cell heights, while stratified columnar epithelium has multiple layers of cells. Pseudostratified columnar epithelium is found in the respiratory tract and functions in secretion and absorption, while stratified columnar epithelium is found in the male urethra and functions in protection.
There are 8 types; simple squamous, simple columnar, simple cuboidal, stratified squamous, stratified cuboidal, stratified columnar, pseudostratified columnar, and transitional.
Simple columnar epithelium is the type of epithelium designed for absorption and secretion found throughout much of the gastrointestinal tract. It is characterized by tall, closely packed cells that have microvilli to increase surface area for absorption and goblet cells for secretion of mucus.
