Overview

Think about a building. It needs a strong structure to stay standing. Your bones are like that structure. They hold your body up and protect important parts inside, just like walls and beams protect what is inside a building.

Bones are hard structures that make up the skeletal system. The human body has about 206 bones. Bones are made of strong materials, including calcium, which helps keep them hard and durable. Bones work with muscles to help your body move. They also protect important organs and help produce blood cells.

 

Parts of the Bones

Bones come in different shapes and sizes, depending on their function.

• Long bones, such as the femur (thigh bone), help with movement.
• Short bones, such as those in the wrist, help with stability and support.
• Flat bones, such as the skull, help protect important organs like the brain.

Inside many bones is a soft tissue called bone marrow. Bone marrow is where blood cells are made.

Joints are places where two bones meet. Joints allow movement in different parts of the body, such as your knees, elbows, and shoulders.

Ligaments are strong tissues that connect bones to other bones and help keep joints stable.

 

Functions of the Bones

Bones have several important functions in the body.

One major function is support. Bones give your body its shape and help you stand upright.

Another function is protection. For example, the skull protects the brain, and the rib cage protects the heart and lungs.

Bones also help with movement by working with muscles.

Another important function is blood cell production. Bone marrow produces red blood cells, white blood cells, and platelets.

Bones also store important minerals like calcium, which the body uses when needed.

 

Common Injuries and Conditions

Bones can sometimes become damaged or weak.

A fracture is when a bone breaks. This can happen from falls or accidents.

Osteoporosis is a condition where bones become weak and more likely to break.

Some people may also have bone infections or other conditions that affect bone strength.

Eating foods rich in calcium and staying active can help keep bones strong.
