Functions: Support & Protection
- Supports the body upright and holds soft tissues and organs in place.
- Protects vital organs: skull shields the brain, ribs guard the heart and lungs.
- Spine safeguards the spinal cord, enabling nerve communication.
3
Movement & Blood Cell Production
- Works with muscles to enable movement via bones as levers and joints.
- Bone marrow in long bones produces red and white blood cells and platelets.
- Essential for activities like walking, running, and fine motor skills.
4
Mineral Storage & Bone Health
- Bones store minerals like calcium and phosphorus for strength.
- These minerals support bone density and other body functions.
- Healthy diet and exercise are crucial for maintaining bone health.
5
Conclusion: Importance of the Skeleton
- The skeletal system is vital for structure, protection, and movement.
- Ensures blood cell production and mineral storage for overall health.
- Maintaining bone health is essential for daily activities and longevity.
