These systems are all working in concert with each other. To play basketball, first you must have a skeletal system (your bones) that give your muscles something to attach to and which allow the muscles something to work off of. So, with your bones and your muscles supplying the ability for movement, your nervous system is what gives the orders and makes the decisions. If you want to move left, your brain has to send that signal down to the muscles necessary to contract to make the movement to the left. In addition, the nervous system of your body is constantly sending information back to your brain about the status of the body–for example, if another player bumps you with his/her elbow in your ribs, then you feel that. Your nervous system sends the message to your brain that you just got hit, so that you can react–by moving away from the hit, or by responding with another move to go around the player. The cardivascular system is the infrastructure that keeps everything working. Your heart, lungs, and blood vessels allow both oxygen and energy (from the food you ate) to go to your muscles as they work, and then again to take away waste product produced from those working muscles. So, the harder you’re running up and down the court, the harder you are breathing to get enough oxygen in, and hence the more your heart will pump, to keep all that blood circulating so that your muscles will have enough to keep giving you the responses you need.
