The left rib cage contains the lungs, heart, stomach, spleen, intestines and pancreas, and the rib cage mainly serves to cushion and protect the internal organs. Because the organs are delicate, they can be easily damaged in case of collision or impact. Therefore, the rib cage is very important for the proper functioning of the internal organs, as it prevents external forces from acting directly on them in the event of a collision or other injury. Without the ribs, a pneumothorax can easily develop if the lungs are hit. Without the protection of the ribs, the heart, stomach, spleen, intestines, pancreas and other organs can be easily damaged and thus unable to perform their normal physiological functions, which can have a significant impact on human health. Therefore, if the rib cage is damaged, it must be treated as soon as possible, otherwise the treatment will be less effective when the internal organs are damaged.
