Answer:
Functions of the bones in the human body:
Support, protection, movement, mineral homeostasis
Explanation:
- Support: the bones provide a rigid support frame for muscles and soft tissues.
- Protection: the bones form several cavities that protect the internal organs from possible trauma. For example, the skull protects the brain against blows, and the rib cage, formed by ribs and sternum protects the lungs and heart.
- Movement: thanks to the muscles that are inserted into the bones through the tendons and their synchronized contraction, movement occurs.
- Mineral homeostasis: the bone tissue stores a series of minerals, especially calcium and phosphorus, necessary for muscle contraction and many other functions. When necessary, the bone releases these minerals in the blood that distributes them to other parts of the body.
