How does the skeletal system function in support, protection, movement, and storage of minerals?

Summary Introduction

To review:

The functionality of the skeletal system in support, protection, movement, and storage of minerals.

Introduction:

The human skeletal system is composed of 206 bones, and the network of tendons, ligaments, and cartilage that connects them. The skeletal system performs vital functions that enable us to survive.

Explanation of Solution

Skeletal system has following main functions:

Support: Bones are hard structures and the cartilages are soft bones; they both provide a structural framework to the body. They also support soft tissues and provide attachment points for the tendons of skeletal muscles.

Protection: The skeleton system acts as an outer shield and protects all internal organs from injury. For example, skull protects the brain and the rib cage protects the heart and the lungs.

Assistance in movement: Most skeletal muscles attach to bones; when these muscles contract, they pull on bones and produce movement.

Mineral homeostasis: Bones jointly make up approximately 18% of the body weight. Bones store several minerals, mainly calcium and phosphorus. Calcium and phosphorus provide strength to the bones. Bones approximately stores about 99% of the body's calcium. When the body needs these minerals, bones release them into the blood to maintain homeostasis and to dispense these minerals to different parts of the body.

Conclusion

Therefore, it can be concluded that the skeleton system provides the framework, which protects different internal organs, provide the support to the body, and also acts as a mineral reservoir.
