Detailed explanation-1: -Columnar epithelium covers the intestinal tract from the end of the esophagus to the beginning of the rectum. It also lines the ducts of many glands. A typical form covers the villi (nipple-like projections) of the small intestine.
Detailed explanation-2: -Simple columnar epithelial cells are some of the most prolific cells in the body, mainly because they can fulfill so many functions. They are found throughout the body’s organ system, including the digestive tract and the female reproductive system. They are found in the respiratory system, including the nasal passage.
Detailed explanation-3: -Enterocytes are the major cell type in intestinal epithelium. They are simple columnar epithelial cells and play important roles in nutrient absorption (e.g., ions, water, sugar, peptides, and lipids) and in secreting immunoglobulins.
