What is a system? A system is a group of mechanisms that is used to do a function (lifting someting off the ground, or pulling snow off the ground, etc.In the world of systems we have learned about two. These are called open and closed. An open system means that at the end of the system there is a opening where a liquid, fluid or substance... pretty much anything, will eventually come out. Examples of this are: A car, because the exhaust comes out the back, the digestive system...if you know what I mean. Whatever comes in must come out, these systems never let the materials inside of them circulate.
Closed System:
This system has no start or stop button. These systems usually run in a circular motion allowing nothing to escape. An example of this is your body's ciculation. Heart pumps oxygen into cells, cells come back to get more oxygen, it is a continuous cycle.
Feedback:
The problem with any system is that without feedback you cannot know whether or not everything is going well. If you are at one end of a conveyor belt you can't see what's coming off of the other side, so it is wise to get FEEDBACK! You're brain is constantly getting feedback from the rest of your body.
