It helps so you can breath and help the heart beat for the blood to flow
The nervous system is designed to work both ways. Since the cells can only operate one way, this means that there is two complete systems.
They are both the same because they both transport stuff;a highway is a transport system for cities. It's also because the cars represent the blood flow in the transport systems.
Your body is the sum of all its systems. There are no "other systems". All the body's systems have to be working together or the body will not be able to stay alive.
Body systems work together to keep the body healthy and the body systems are interdependent (they rely on each other).
as the body's systems get older, they require more blood flow to operate, thus causing increased heart rate
Western medicine generally does not endorse any of the traditional Chinese healing systems that utilize the concept of energy flow in the body,
the lungs take in oxygen and all other systems need oxygen to respire and work
Keeping the body perfect is the same as homeostasis i.e. maintenance of internal environment. There are control systems in body which coordinate the functioning of different systems. There is asset point for variable so that various variable characteristics of internal environment are kept in healthy range. The control systems [usually neuroendocrine] have positive and negative feed back mechanisms and feed back gains to achieve homeostasis, i.e perfect body. For example these systems increase the blood flow to stomach after food and increase breathing heart rate to get more oxygen after muscular exercise.
