The Main Functions of the Human Skeletal System

The human skeletal system serves several important functions in the body:

1. Support: The bones provide framework, support and shape to the body.
2. Protection: The skeletal system protects vital organs such as the brain, heart, and lungs.
3. Movement: Bones, along with muscles, allow movement and mobility.
4. Blood Cell Production: The bone marrow inside the bones produces red and white blood cells.
5. Mineral Storage: The bones store essential minerals, such as calcium and phosphorus.

In conclusion, the human skeletal system plays a crucial role in maintaining the structure and functionality of the body.
