muscular system
Flesh that moves
The muscular system is the network of tissues in the body that produces movement.
It includes skeletal muscles that move bones, smooth muscles that line organs and blood vessels, and cardiac muscle in the heart.
The system works with the skeleton to enable locomotion, posture, and bodily functions from breathing to digestion.
