Many scientists would agree that the chest is perhaps the most vital region in the entire human body. The thorax is home to critical organs in the body, such as the heart, lungs, and aorta. The body has developed a series of defenses to protect one of the most significant regions in the body. At the top of the list of the bodies defenses are the bones. In the thorax or chest region, the chest bones can be found.
Many people know what the skeletal system bones look like. However, not many people know the structure of these bones. The bones are formed from calcium phosphate and a type of dense connective tissue. The bones of the skeletal system all have distinct shapes and sizes. The skeletal bones are very important in aiding the body with movement and strength.
One key function of the bones that is often overlooked is the production of red and white blood cells. The bone marrow is located in the center of many bones in the skeleton. In this region, red blood cells and white blood cells are produced. These red blood cells are very significant for the body’s function because the carry oxygen to cells in the body. The white blood cells are also very important for bodily function because these cells play a role in defending the body from pathogens.
In the chest, there are 25 bones. The thorax contains twenty four ribs out of the total twenty five bones in the chest. The sternum is the other bone that makes up the chest. All of the thorax bones play important functions in protecting the chest organs. The ribs are curved skeletal bones that form a structure known as the rib cage around the lungs and heart. Along with protecting the heart and lungs, the ribs allow breathing by expanding and compressing. The other bone of the chest, the sternum, is found in the center of the chest. It’s role is protection of the heart primarily.
These chest bones play an essential role in human survival and existence. The lack of the chest bones would allow the easy damage of the circulatory and respiratory organs. Since
evolution drives organisms to survive, humans have evolved to develop these thorax bones to protect the lungs and heart. The thorax bones are responsible for 25 out of 206 bones in the human body skeleton.
