All of the systems within the body interact with one another to keep an organism healthy. Although each system has specific functions, they are all interconnected and dependent on one another. The nervous system controls various organs of the body directly.The brain also receives information from many organs of the body and adjusts signals to these organs to maintain proper functioning.
