The cardiovascular system is a very interesting system and major part of the body. This is the system that helps us breathe and regulates blood and oxygen in our blood. This system consists of the pulmonary circulation and coronary circulation. I think it is fascinating how this system removes waste and helps our body maintain homeostasis or balance. If it were not for this system, waste would build up in our bodies. I'm still a little confused about the direction of each circulation but I know it flows throughout the whole body.
