Ribs anatomy explained: Includes images, video, and free quiz. Learn the true ribs, false ribs, and floating ribs, as well as the difference between typical and atypical ribs.

The human rib cage is a component of the human respiratory system. It encloses the thoracic cavity, which contains the lungs. An inhalation is accomplished when the muscular diaphragm, at the floor of the thoracic cavity, contracts and flattens, while the contraction of intercostal muscles lift the rib cage up and out.
