The human body is a complex system of organs and tissues that work together to keep us alive. The human brain is responsible for controlling all of our movements, thoughts, and emotions. It sends signals to the rest of the body through the nervous system, which includes the spinal cord and nerves. The heart pumps blood throughout the body, delivering oxygen and nutrients to all of its cells. The lungs take in oxygen from the air we breathe and expel carbon dioxide. The digestive system breaks down food into nutrients that can be absorbed by the body.
