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.

â¢ Both connective and epithelial tissues mainly have a structural function. They both consist of a strong fibrous component. But apart from that differ immensely. â¢ The connective tissue forms the sub types of skeletal tissue, forming strong bones and muscle, as well as fluid tissue such as blood and lymph.But the epithelium rarely shows a variation in tissue structure apart from the number of layers of cells.pithelium. Epithelial tissue is arranged in single or multilayer sheets, and it covers the internal and external surfaces of an organism. True epithelial tissue arises from the embryonic ectoderm, which provides epithelium for the skin, nervous system and parts of the mid gut and the hind gut.
