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.his cell type is found primarily in duct systems (Cuboidal 2) or as the collecting tubules in kidney (Cuboidal 3). Simple columnar epithelium-cells taller than wide w/ many subtypes. It forms most of the large ducts in the body (Columnar duct) and the lining of absorptive cells in the gut (Columnar Absorptive 1).
Mucous membranes, also called mucosa, line the inside of cavities that open directly to the exterior environment. Mucous membranes line the gastrointestinal tract, respiratory tract, reproductive tracts and the urinary tract.This type of membrane is composed of an epithelial cell layer and an underlying connective tissue layer.The epithelial layer is an important defense mechanism that prevents the entry of pathogens and microbes into the body. The cells are tightly packed together, so fluid cannot leak through the epithelial layer.his type of membrane is composed of an epithelial cell layer and an underlying connective tissue layer.
