| work in communication and coordinating activities | nervous tissue |
| flat cells for rapid passage of substances | squamous epithelium |
| square, allow secretion and absorbtion | cuboidal epithelium |
| taller and offer more protection, allow secretion and absorbtion, may have villi or cilia to increase surface area | columnar epithelium |
| change shape, go from cuboidal to flat by stretching, located in bladder | transitional epithelium |
| move mucus and particles in trachea and upper respiratory tract | ciliated simple columnar epithelium |

| the material between cells | matrix |
| very strong, make up 25% of protein, found in most connective tissue, contains vitamin c and msm nutrient | collagen fibers |
| smaller and have ability to stretch up to 1 1/2 times their original size and return, contain elastin | elastic fibers |
| thin fibers support vessel walls and provide framework for organs, and help form basement membrane | reticular fibers |
