A
  1. Protection of vital organs - The skeleton protects the most important internal organs from injury.

    • mineral homeostasis bones act as reservoirs storing vital minerals used for muscle contraction and nerve activity
    • energy storage, lipids stored inside yellow bone marrow
  3. Blood Cell Production (haemopoeisis) - RBCs, WBCs and platelets produced in red bone marrow
