The human body is made up of several organ systems that work together as one unit. There are ten major organ systems of the body. Some of these systems include the:
  • circulatory system
  • digestive system
  • nervous system
  • reproductive system

It is important to keep in mind that these systems don't just exist as individual units. The final product of these cooperating systems is one unit called the body.
