How is the skin, the largest organ in the body, constructed? The skin has two layers: the upper layer is the epidermis, and the lower layer is the dermis. Below the dermis is the hypodermis, or subcutaneous layer, composed of fat or other connective tissue. The epidermis itself is an epithelium made up of sublayers.The outermost portion consists of many layers of flat, dead, dry epithelial cells called keratinocytes. Clearly this barrier of dead cells needs no blood supply. The waxy surface coating of these cells allows the skin to be waterproof and dry.he epidermis itself is an epithelium made up of sublayers.

Types of non-keratinized epithelium include tissue that lines the esophagus. Skin is made up of epithelial tissue. Transitional epithelium is found only in the urinary system structures of the renal pelvis, bladder ureter and urethra.The urothelium is tissue found in the bladder that helps prevent previously filtered wastes from getting back into the bloodstream.here are also two specialized types of stratified epithelium: keratinized and transitional. Keratinized epithelial tissue is found only on the external surfaces of the body, including the inside of the mouth.
