The human body is a complex machine that is made up of many different parts, all working together to keep us alive and functioning properly. The brain, which is the control center of the body, sends signals to the muscles through the nervous system, telling them when to move and how to move. The heart pumps blood throughout the body, supplying oxygen and nutrients to the cells. The lungs take in oxygen from the air we breathe and release carbon dioxide as a waste product.
