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 supports, protects, and binds other tissues together. The collagen fibers that are found between connective tissue cells provide strength and flexibility. Some examples of connective tissues are bone, cartilage, blood, and adipose (fat).Blood is the main connective tissue in the circulatory system, but it's a liquid connective tissue. Blood tissue is in the same family as bone and cartilage, but instead it has a liquid medium that holds it together.The blood's volume is 55% plasma, 44%red blood cells, and 1% platelets and white blood cells.ome examples of connective tissues are bone, cartilage, blood, and adipose (fat).
