Tissues consist of a group of cells with similar structure performing similar function. Tissues constitute organs. Animal tissues are of four major types : epithelial, or covering tissue; connective, or supportive tissue; muscular, or contractile tissue and nervous tissue.
This is the thin protective layer of cells which covers the surface of the body and lines the internal organs. The cells are generally packed close together. The shape of the cells depends on the location and function of the tissue. And based on the shape of the cells, epithelial tissue is classified into four types—squamous, cuboidal, columnar and ciliated. Epithelial tissue originates from the ectoderm. But, epithelial tissue lining the intestine originates from the endoderm.
