They serve several important functions:

  1. Support: Bones provide structural support for the body, giving it shape and form. They form the framework that supports muscles, organs, and tissues.
  2. Protection: Bones protect vital organs such as the brain, heart, and lungs. For example, the skull protects the brain, while the rib cage protects the heart and lungs.
  3. Movement: Bones, along with muscles and joints, facilitate movement. Muscles attach to bones via tendons, and when muscles contract, they pull on the bones, causing movement.
  4. Storage: Bones serve as a reservoir for minerals such as calcium and phosphorus, which are essential for various bodily functions. These minerals can be released into the bloodstream as needed.
  5. Blood cell production: Within the bone marrow, specialized cells called hematopoietic stem cells produce various types of blood cells, including red blood cells, white blood cells, and platelets.
