What is the Purpose of the Skeletal System and How Many Bones are There in the Adult Human Body
The skeletal system is a complex framework of bones that provides support, protection, and movement for the human body. It is made up of 206 bones that are connected by joints, ligaments, and tendons.
The skeletal system protects the body's vital organs from injury. The skull, for example, protects the brain, while the rib cage protects the heart and lungs. The bones also help to produce red blood cells and store minerals such as calcium and phosphorus.
The skeletal system allows for movement. Bones provide levers for muscles to pull on, which allows us to move our bodies. For example, the biceps muscle contracts to bend the elbow, while the triceps muscle contracts to extend the elbow.
The number of bones in the adult human body varies from person to person. The most common number is 206, but some people have more or less bones. For example, some people have an extra bone in their foot, while others have a fused bone in their spine.
