Expert Answer:

The body of living organisms is made up of an important framework of bones called the skeletal system or the skeleton. The skeleton consists of bones, cartilages, ligaments, tendons and fascia. 
 
Functions of Skeleton:
  1. Support and shape: The skeletal system provides a framework to the body. It provides support to all soft parts and gives a definite shape to the body and all body parts.
  2. Protection: The skeleton protects the internal delicate and important organs of the body. For example, in human beings, the skull protects the brain, ribs protect the heart and lungs, the vertebral column protects the spinal cord etc.
  3. Movement: The skeletal system helps in movement. It co-ordinates the movement of attached bones and muscles to bring about locomotion.
  4. Leverage: Some bones and joints of the skeletal system form levers and help in increasing either the movement or the force. For example, slight contraction of the biceps moves the hand to a distance of about a foot.
  5. Formation of blood cells: The skeleton is the site of haematopoiesis. Various types of blood cells such as red blood cells, white blood cells and platelets are formed in the bone marrow of some long bones.
  6. Storehouse for minerals: The bones are a storehouse of calcium and phosphorus for the rest of the body.
