Body System
Well to start off, how does the body work as a whole? Well first we have to consume energy to create energy. Thus our digestive system has to break down the foods to collect and use the energy. The energy that was collected from the food is then sent to the heart to get modified and transported to the rest of the body. This energy is nutrients and blood. The blood is then carried through the respiratory system. This system is where oxygen is transported so that we can breathe, and CO2 waste is transported out of the body. After that stage, the blood will go through out the body. This blood can benefit our muscular system, nervous system and much more. How does the nervous interact with the rest of the body? That's a whole different story. The nervous system is like the lasers on a automatic light. The nervous system collects the data and transport it to the brain. Just like the laser senses a close object and signals the light to turn on. Without it the body would fail because it won't be able to maintain homeostasis.
Space Effects
How will long term space travel effect the body? In space we are expose to many radiations. These radiations could damage or potentially kill our nerves. Like said in the automatic light analogy, without the nervous system we would not be able to maintain homeostasis. This is because everything is out of whack. Nothing is submitting information to the brain to react to. Without "directions" from our brain, our body systems would shut down and then our bodies would not be able to function, and we may die in the end.
