Columnar Epithelial Tissue.

They are located in the small intestine and help with absorption of nutrients from digested food. They also increase a cells surface area
protection, absorption, filtration, excretion, secretion, and sensory reception
This type of epithelium is frequently found in glands, and the pancreas, where its function is secretion.
The function of epithelial tissue include: transportation of materials, protection of underlying tissues, absorption of water and nutrients and secretion of waste products.
Absorption of nutrients and water.
The two primary roles of the digestive process are absorption and secretion. The role of absorption in the digestive system is vital to the body because without it, the vitamins, minerals, carbohydrates and other nutrients we consume could not be used. Absorption is the process by which the nutrients in food are passed on to the blood. The majority of absorption occurs in the small intestine, the digestive tract's primary organ. After food passes through the stomach to the small intestines, it is turned into energy for the body to use. Absorption is made possible by the villi, small bristle-like protrusions in the mucosa. The mucosa is the moist tissue lining certain parts of the body's passages and organs. The villi act as channels through which the nutrients derived from digested foods can pass into the bloodstream and be carried to the rest of the body. The actual absorptionprocess is slightly different for each type of nutrient.

Their function is to digested unwanted materials.They contain digestive enzymes.
The function of the ciliated epithelium of the tracheobronchial tree is secretion and absorption. These cells control the mucus produced.
increase intestine surface area for more efficent absorption of digested nutrients
Villi are largely present in the lower digestive tract. Their function is not only to absorb the digested foodstuffs but also they greatly increase the surface area for absorption.
The primary function of the digestive system is to supply the cells of the body with nutrition. It does this by ingestion, digestion, and absorption. The waste materials that are not used are then eliminated.
