The human body is a complex machine made up of many different systems that work together to keep us alive. The circulatory system pumps blood throughout our bodies, delivering oxygen and nutrients to our cells and organs. The nervous system transmits messages between our brain and the rest of our body, allowing us to think, move, and feel sensations. The digestive system breaks down food into nutrients that are absorbed by our body, giving us energy and fuel for growth.
