what is rib cage ?

In humans, the rib cage is located in the upper body and consists of 24 bones that serve the purpose of protecting many vital organs. These 24 bones are divided into two sections of 12 on both sides of the body. The heart, lungs, and parts of the stomach are all located inside the rib cage. It is sometimes referred to as the thoracic cage because it is a major part of the thoracic cavity in the human body. In addition to protecting vital organs, the rib cage also helps a person breathe properly.

There are 12 ribs and 12 vertebrae that make up the thoracic cage. These bones are all slightly curved in shape and are connected to the spinal column. The ribs that are attached directly to the sternum are known as true ribs. Ribs that are not connected to the sternum are called false ribs and are attached to the true ribs. The bottom two ribs are attached directly to the spine and are known as floating ribs.

When a person inhales, the ribs are lifted up by muscles. This gives the lungs enough room to expand so they can take in enough air. The ribs lay back down on top of the lungs when a person exhales. This action presses the lungs inward and helps push air out.
