The nasopharynx is lined with respiratory epithelium, which consists of pseudostratified ciliated columnar epithelial cells. These cells have cilia that help trap and move mucus and particles along the respiratory tract for removal.
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.
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.
The eight types of epithelium include simple squamous, simple cuboidal, simple columnar, stratified squamous, stratified cuboidal, stratified columnar, transitional, and pseudostratified columnar epithelium. Simple squamous epithelium lines blood vessels and alveoli in the lungs; simple cuboidal is found in kidney tubules; simple columnar lines the gastrointestinal tract. Stratified squamous epithelium protects the skin and oral cavity; stratified cuboidal is found in sweat glands; stratified columnar is located in parts of the male urethra; transitional epithelium lines the bladder; and pseudostratified columnar epithelium is found in the respiratory tract.
The layer of the digestive tract that is composed of stratified and columnar epithelium is the mucosa. This layer is responsible for absorption and secretion in the digestive system.

psuedostratified columnar ET
pseudostratified columnar 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.
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.
psuedostratified epithelium
Pseudostratified ciliated columnar epithelium lines most of the respiratory tract. This type of epithelium helps to trap foreign particles and move them out of the respiratory system with the help of cilia.
Simple = One layer Columnar = tall (column like) cells Epithelium = Lining, covering, and glandular tissue Simple columnar epithelium = A single layer of tall cell tissue
Columnar epithelium.
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.
