Line 1: Line 1:
 +(1) Epithelial relates to the layer of [[cell]]s which form a covering over the internal and external surfaces of the body. Examples of this would be the inner lining of the [[lung]]s, digestive tract, and [[skin]] cells.
 +(2) There are two main types of epithelial tissue: lining and glandular. You can develop colorectal [[cancer]] in both of them. Cancer of epithelial tissue is called a [[carcinoma]].
 +[[Epithelial Lining Tissue]]
 +This type of epithelial tissue does what it sounds like it does: lines things. What structures it lines depends on whether the lining is simple or stratified.
 +Simple [[epithelium]] is one layer thick and lines the respiratory tract, [[blood vessels]], and glands in the digestive tract, including glands in the large intestine.
 +Stratified epithelium is several layers thick and lines the skin, mouth, and anal canal. Squamous cell carcinoma is an example of a cancer that develops from lining epithelium.
 +[[Epithelial Glandular Tissue]]
 +Glandular epithelium forms glands. Glands secrete things and are classified as endocrine or exocrine. Endocrine glands secrete things into the [[bloodstream]],​ like hormones. Exocrine glands secrete things that go outside of the body, like mucus and sweat. Cancer of a gland is called adenocarcinoma.
