SYSTEMS WORKING TOGETHER IN AN ORGANISM
The nervous system, gives instructions via electrical pulses to every nerve as to what job it is to perform and how to react in different situations it's basically the control system of an organism. It tells all the organs to perform the jobs they are assigned to do, so without the nervous system the body would be full of organs unable to perform a job.
The digestive system breaks down nutrients that enter into the bloodstream transferring the nutrients into the blood in the circulatory system. The digestive system dissolves your food with enzymes so it can provide the body, organs and muscles with energy to perform.
The circulatory system pumps blood into the lungs and the lungs pump oxygen into the blood, with out the interaction between the respiratory and circulatory systems our muscles couldn't receive oxygen forcing the body to shut down. The skeletal system protects all these organs and systems, and the muscles are responsible for much of the action in the organs on top of being connected to the bones of the body for mobility. Without the interaction between all body systems in an organism the body would not be able to function.
