Terms | Definitions |
|---|---|
 simple squamous | 1 layer thick; flattened in shape; used in diffusion and filtration; found in air sacs in lungs, lining of blood vessels (exchange takes place in capillaries) |
| simple cuboidal | Single layer of cube shaped cells, usually with spherical nuclei. Covers ovaries and lines most of the kidney tubules and the ducts of certain glands. |
| simple columnar | single layer of column shaped cells. Secretion (mucous) and absorption. Surface lining of stomach and intestines. |
| pseudostratified columnar | looks stratified or looks like in layers, but really just odd shaped columnar cells with nuclei located in different parts of each cell. Found in the cells of the respiratory system. |
| Stratified squamous | layers of flattened cells; used in protection (covers areas of high abrasion); found in skin and upper digestive tract (mouth, esophagus) |
| stratified cuboidal | 2-3 layers of cubed shaped cells, lines ducts of mammary, salivary and sweat glands |
| stratified columnar | Located in pharynx (back of throat), male urethra; 2 or more layers of elongated column-shaped cells |
| Transitional Epithelium | Multiple layers of cells which appear cuboidal when not stretched, but squamous when stretched; found in the urinary organs |
| Endocrine gland | any of the glands of the endocrine system that secrete hormones directly into the bloodstream |
| Exocrine gland | A gland that secretes its product into a duct, which ultimately carries the product to the surface of the body or into a body cavity. Some examples of exocrine gland and their products are sweat glands (sweat), gastric glands (acid, mucus, protease), the liver (bile), sebaceous glands (oil), and lacrimanl glands (tears). |
