Functions of the Skeleton:

• Provides Structure: Supports the body and maintains shape.

• Facilitates Movement: Acts as levers that muscles pull on to produce motion.

• Protects Vital Organs: Encases and safeguards organs (e.g., brain, heart).

• Produces Blood Cells: Hematopoiesis occurs in the bone marrow.

• Stores Minerals: Serves as a reservoir for minerals, particularly calcium and phosphorus.
