muscular system
human body
Without muscles you couldn't open your mouth, speak, shake hands, walk, talk, or move your food through your digestive system. There would be no smiling, blinking, breathing. You couldn't move anything inside or outside you. The fact is, without muscles, you wouldn't be alive for very long!
Skeletal system
The Skeletal system has three major jobs:
1. It protects our vital organs such as the brain, the heart, and the lungs.
2. It gives us the shape that we have.
3. It allows us to move. Because muscles are attached to bones, when muscles move, they move the bones and the body moves
