Knees help us walk, run, and jump. Think of your knee like a door that opens and closes, it lets you bend your leg to sit down or stand up. Inside the knee are bones, muscles, and soft tissues working together to make sure everything moves smoothly.
Examples
- A child bends their knee to sit on the floor.
- A person stretches their leg while walking.
- A dancer jumps and lands with both knees bent.
