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.

Connective tissue is composed primarily of two elements: cells and a matrix. The types of cells found in connective tissue vary depending on the type of tissue they support. For example, red and white blood cells are found in blood, which is a fluid connective tissue.Adipocytes are fat cells found in adipose tissue, or fat. And fibroblasts are cells found in large quantities in many different types of connective tissues.reolar and reticular tissue are types of loose connective tissue that provide support, as well as fill up unused spaces in the body. Blood, a fluid connective tissue, provides a transport system within our body for oxygen and other important substances.
