the difference between connective and epithelial tissue
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.
