The Skeletal System

 

The human skeleton consists of 206 bones, many of which move or hinge at joints and which, enable the body to achieve a variety of actions, such as running, throwing, striking, pulling and pushing. The human skeleton was created by evolution to perform six functions:

  1. To provide a lever system against which muscles can pull
  2. To provide a large surface area for the attachment of muscles
  3. To protect delicate organs (i.e the cranium protects the brain)
  4. To give shape to the body
  5. To give support to the body (i.e the firm construction of the thorax that permits breathing)
  6. To manufacture red blood cells and store fat, calcium and phosphate

The Muscular System

 

One of the important functions of the human body is to enable movement. Physical activity is achieved as a result of over 600 muscles that contract or shorten, thereby facilitating the movement of the skeleton across its joints. Muscles are the converters of energy.
