There are four major tissues: (1) Epithelial tissue, also called epithelium, covers body surfaces and organs and lines body cavities; (2) Connective tissue binds and supports body parts; (3) muscular tissue contracts; and (4) nervous tissue responds to stimuli and transmit impulses from one body part to another.
Epithelial tissue comprises one of the four basic tissue types. The others are connective tissue (support cells, immune cells, blood cells), muscle tissue (contractile cells), and nervous tissue. Organs represent various combinations of these four basic tissue types, which thus comprise the entire body.
