Besides the skin what are the other coverings of the body?
Besides the skin there are other covering tissues made of epithelium over other tissue layers. They are the tissues that cover the internal surfaces of hollow organs, like the organs of the digestive tube, the airway, the renal tubules, the ureters, the bladder, theurethra and the blood vessels. The glands and the serous membranes are made of epithelial tissue too.
