Epithelium (epi- + thele + -ium) is one of the four basic types of animal tissue. The other three types are connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body.There are three principal shapes of epithelial cells: squamous, columnar, and cuboidal.he other three types are connective tissue, muscle tissue and nervous tissue.

Fibrous connective tissue is mostly made of proteins and water, and ligaments and tendons are also made of it. In the stomach, its primary purpose is to separate the mucosa from the smooth muscle layer of the stomach wall.ust outside the epithelial tissue is the lamina propria. This is a thin layer of loose connective tissue that contains a moist lining of mucous membranes. Together with the epithelial tissue, it makes up the mucosa, which secretes gastric acid to aid in digestion. It also absorbs nutrients from the stomach.
