Dark purple nuclei. Epithelial Tissue Location. The main function of a simple cuboidal epithelium is the production or absorption of substances. This epithelial type is found in the walls of capillaries, linings of the pericardium, and the linings of the alveoli of the lungs. The cells in the stratified columnar epithelium, as in the case of simple columnar epithelium are taller than they are wide. •Mesothelium is the epithelium forming serous membrane lining internal body cavities: Peritoneum, Pleura and Pericardium. Naming of the simple squamous epithelium depends on the location: •Endothelium is the lining of the blood vessels, lymph vessels and the heart. Lining of gall bladder. Simple squamous epithelium is of common occurrence in the body; chief examples are: (1) endothelium which covers the internal surface of heart, blood vessels and lymph vessels, (2) mesothelium which lines the pericardial, pleural and peritoneal cavities, and (3) the lining epithelium of the alveoli of the lung. Simple squamous epithelium is a type of epithelial tissue characterized by a single layer of squamous epithelial cells.Epithelium lines most of the body’s organs and constitutes one of the body’s main tissue types, along with nervous, connective, and muscle tissue.Epithelium is divided by form and function into three main types: cuboidal, squamous, and columnar.
