Kavi Flexes and Jumps
Kavi stands up tall, bends an arm, and feels a firm bump pop up — a muscle! 💪 "Whoa! Inside me there's a strong frame of bones 🦴 that holds me up and keeps my shape. And joined to my bones are soft muscles that pull to make me move. My skull guards my brain, my ribs guard my heart and lungs, and together my bones and muscles let me bend, walk, and jump! Come and see how your body moves!"

A peek inside
Kavi stands up tall and does not fall over. What part inside Kavi holds the body up and gives it shape?
The skeleton is all the bones together. Bones are hard, so they support the body and keep its shape.
