What is Tissue."Human body tissue makes up organs and other body parts. There are four main types of tissue: muscle, epithelial, connective, and nervous. Each is made of specialized cells that are grouped together according to structure and function. "

The muscular system has 3 main muscles skeletal, cardiac. and visceral. The first is the skeletal muscle. It contracts to move parts of the body closer to the bone that the muscle is attached to.The skeletal muscle works with the skeletal system because it moves other parts of the body closer to the bone.
