the body surface and forms the lining for most internal cavities. There are two kinds of epithelial tissues: Covering and lining epithelium covers or lines almost all of your internal and external body surfaces; for example‚ the outermost layer of your skin and other organs‚ and the internal surface lining of your lymph vessels and digestive tract. Glandular epithelium secretes hormones or other products such as stomach acid‚ sweat‚ saliva‚ and milk. Function and shapes of epithelial tissue:
