Examples of how your bones help you stand and play.

🦴 Quick Study Guide

• 💪 Bones provide a rigid framework, allowing us to stand upright against gravity.
• 🤸 Joints, where bones meet, enable movement like running, jumping, and throwing.
• 🛡️ Bones protect vital organs; for example, the rib cage protects the heart and lungs during sports.
• ⚙️ Muscles attach to bones via tendons, allowing for coordinated movements necessary for playing.
• 🧪 Bone marrow produces blood cells, essential for delivering oxygen to muscles during physical activity.
• 💡 Weight-bearing bones, like the femur and tibia, are strong and resilient, supporting our body weight during standing and playing.
