The human body is made up of more than 60 billion cells. These cells are grouped together to form organs such as the heart and lungs, which work together to keep us alive. Our bodies also contain a network of nerves that connect our brain to the rest of the body, allowing us to feel sensations like pain and pleasure. Additionally, we have a system of blood vessels that carry oxygenated blood throughout the body, providing it with the nutrients it needs to function properly.
