What Are Bones?

Bones are the strong, hard parts inside your body that help you stand, move, and protect your organs. Every person, from babies to grown-ups, has bones that make up their skeleton. These bones give your body shape and help you do many things every day!

How Many Bones Do You Have?

When you are a baby, you have about 300 bones. As you grow, many of these bones join together. By the time you are a grown-up, you have 206 bones. The biggest bone in your body is called the femur. It is in your leg and helps you walk and run. The smallest bone is very tiny and is called the stapes. It is in your middle ear and helps you hear sounds.

What Do Bones Do?

Bones have many important jobs. They protect your body’s special parts, like your brain and heart. They also help you move by working with your muscles. Bones are like strong towers that hold up your body. They even help make new blood cells and store important things like minerals, such as calcium, which keeps your bones strong.

Different Kinds of Bones

There are different shapes and sizes of bones in your body. Some are long, like the bones in your arms and legs. Others are flat, like the bones in your skull. There are also small bones called sesamoid bones that help your tendons move smoothly. All these bones work together to keep you healthy and moving!
