• The average human adult skeleton has 206 bones joined to ligaments and tendons to form a protective and supportive framework for the attached muscles and the soft tissues which underlie it.
  
• The nervous system is the body's information gatherer, storage center and control system.
  
• The body is made up of a set of levers, whose movements copy the geometry of classical mechanics.
  

• The digestive system is a group of organs that work like wrecking equipment to break down the chemical components of food, through the use of digestive juices, into tiny nutrients which can be absorbed to generate energy for the body.
