The human body is made up of several systems that work together to keep it functioning properly. The skeletal system provides a framework for the body, while the muscular system allows for movement and support. The nervous system sends signals from the brain to the rest of the body, controlling everything from basic functions like breathing and digestion to more complex actions like walking and talking. The circulatory system transports blood throughout the body, supplying it with oxygen and nutrients.
