Discover how the kidneys, at only 4 inches long, process the body’s entire blood volume approximately 15 times each hour, 24 hours a day. Fantastic close-up photography shows the very cells that give our bodies substance and together make it run like a well-oiled and highly sophisticated machine. Front cover: A colored X-ray of the chest of an adult woman shows healthy lungs and heart. The two lungs — in blue and orange — can be seen through the ribs on each side of the central breastbone. The lungs supply the body with oxygen and carry away carbon dioxide. The heart — in deep red — occupies the space at lower center right. It pumps blood to and from the lungs and throughout the body.
