The muscular system consists of all the muscles in the body.
The muscular system:
- Enables the body to move.
- Gives the body its shape.
- Protects organs, such as the liver.
Muscles can change in length:
- When they contract, they become shorter and thicker.
- When they relax, they return to their original length and thickness.
Tissues called tendons connect muscles to bones.
