Epithelia are grouped into two general classes: (1) Epithelial Membranes - covering or lining of the body (skin or stomach lining) and (2) Glandular Epithelium - for increased secretion epithelial cells grow down into the connective tissue and form glands.

The mucosa of the small intestine is characterized by evagination into plicae and villi, which increase the surface area for nutrient absorption, and by short tubular invaginations, the crypts, which provide a protected site for stem cells.

Most epithelial tissues are essentially large sheets of cells covering all the surfaces of the body exposed to the outside world and lining the outside of organs. Epithelium also forms much of the glandular tissue of the body. Skin is not the only area of the body exposed to the outside. Other areas include the airways, the digestive tract, as well as the urinary and reproductive systems, all of which are lined by an epithelium. Hollow organs and body cavities that do not connect to the exterior of the body, which includes, blood vessels and serous membranes, are lined by endothelium (plural = endothelia), which is a type of epithelium.

Epithelial cells make up primary tissues throughout the body. Epithelial cells form from ectoderm, mesoderm, and endoderm, which explains why epithelial line body cavities and cover most body and organ surfaces.[1] There are many arrangements of epithelial cells, such as squamous, cuboidal, and columnar, that organize as simple, stratified, pseudostratified, and transitional. Since epithelial cells are prevalent throughout the body, their function changes based on location. For example, epithelial cells in the skin provide protection, whereas they have secretory and absorptive properties in the gut. This article seeks to explain the anatomical characteristics of epithelial cells and their functions and describe features evident upon histological staining.[2][3]

The digestive system is responsible for the ingestion and digestion of dietary substances, the absorption of nutrients, and the elimination of waste products. The secretions of the associated glandular organs, such as the salivary glands, pancreas, liver, and gall bladder, aid the GI tract in accomplishing these functions. This laboratory will focus on the sequential segments of the gastrointestinal tract; the subsequent laboratory will focus on the glandular organs.

Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
