Floating ribs are a set of two pairs of ribs in the human body that do not attach to the sternum or breastbone. They are located at the bottom of the rib cage and are known as the 11th and 12th ribs. Unlike other ribs, floating ribs are only connected to the spine at the back, providing some flexibility and protection to the organs in the lower torso. These ribs play a role in the overall structure of the rib cage, which protects vital organs such as the heart and lungs. While they are not directly involved in breathing like other ribs, floating ribs contribute to the overall stability and movement of the torso during various activities.
