Histology: Epithelial Tissue

Stratified squamous epithelial tissue is found in areas where mechanical stress is common, such as the sole of the foot and the mucosa of the vagina. It is not typically found in the inner lining of the small intestine, lung alveoli, or the cornea of the eye.

Simple Columnar Epithelial Tissue is found in the internal surface (mucosa) of the small intestine where it helps with absorption and secretion. It is not found on the external surface of the skin, lining of the stomach, or heart muscle (myocardium).

Simple Cuboidal Epithelial Tissue is found in kidney tubules, where it aids in absorption and secretion functions.

Pseudostratified columnar epithelium with cilia is specifically found in the mucosa of the trachea, where the cilia help to move mucus and foreign particles out of the respiratory tract.

Simple Squamous Epithelial Tissue is a single layer of flattened cells that is well-suited for diffusion. It is commonly found lining the inner surfaces of blood vessels and the heart to allow for easy nutrient and gas exchange.

Transitional Epithelium is a type of tissue found in organs that need to stretch and accommodate fluctuations in volume, such as the bladder. The stomach, liver, and lungs do not typically have Transitional Epithelium lining.
