- - The human body consists of 4 main types of tissues:
- ) Epithelial tissue lines and protects many parts of the body on both inside and outside surfaces.
- ) Muscle tissue allows movement to occur in all parts of the body
- ) Nervous tissue sends signals through the body to allow cells to communicate.
- ) Connective tissue provides support with structural connective tissue, transports with sequestering connective tissue, and maintains health with defensive connective tissue.
