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.

EPITHELIUM â¢ epithelium is a tissue composed of a layer of cells.â¢ Epithelium lines both the outside (skin) and the inside cavities and lumen of bodies.â¢ The outermost layer of our skin is composed of dead stratified squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities.unctions of Epithelial Tissue â¢ Protection â¢Epithelial cells from the skin protect underlying tissue from mechanical injury, harmful chemicals, invading bacteria and from excessive loss of water. â¢ Sensation â¢Sensory stimuli penetrate specialised epithelial cells.
