Surface epithelium: outer covering of skin and some internal organs. Inner lining of blood vessels, ducts, body cavities, and the interior of the respiratory, digestive, urinary, and reproductive systems: classification: Stratified(multilaminar) epithelium: consists of two or more layers of cells that protect underlying tissues in location where there is wear. Simple squamous epithelium: endothelium: lines heart, blood vessels, lymphatic vessels, mesothelium: forms epithelial layer of serous membrane, *filtration, secretion, diffusion. Simple cuboidal epithelium: lines ovaries and kidneys and certain glands to secrete and absorb. Stratified squamous: protection: keratinized: tough layer at apical surface, superficial layer of skin, non-keratinized: moistened by mucus from salivary glands, mouth, esophagus, vagina. Stratified cuboidal: rare, male uethra and ducts of sweat glands, protection/limited secretion an absorption. Loose: loosely arranged between cells: areolar: fibers and random organization of cells in semifluid ground substance, one of the most widely distributed connective tissues in the body, cells:
