MT 30 LEC – AA (HISTOLOGY ART) 1 year, 3 months ago Epithelial tissue are characterized as large sheets of cells covering surfaces of the body either exposed to the external environment and lining internal body cavities. They are classified according to the shape and number of cell layers present.The figure below includes two types:
Simple squamous epithelium appear as thin scales, with flat, horizontal, and elliptical nuclei. Due to their thinness, they are present where rapid passage of chemical compounds is necessary such as the lining of capillaries and the small air sacs of the lung.
Stratified cuboidal epithelium consists of multiple stacked layers, which protects against physical and chemical damage. This is primarily found in the larger ducts of exocrine glands, (i.e. pancreas, salivary glands, sweat glands).
