| | Epithelium |
 | | Epithelium plays an important role in homeostasis of the body and in maintaining the physiological parameters of the internal environment different from those outside the body. | | | Stratified squamous epithelium is found in the esophagus and epidermis of the skin. | | | Epithelium lines the surfaces of the body and is mainly located on the borders between the external and internal environments. |

| | The best example of stratified squamous epithelium, however, is the skin: the general body surface is covered with it, as slides 7 and 11 demonstrate. | | | A good example of the mitotic activity of epithelia is found in the intestine, slides 40 and 41. | | | Slide 7 is made from thin skin; slide 11 is thicker skin. |
