Many scientists would agree that the chest is perhaps the most vital region in the entire human body. Inside the chest, the heart, lung, and arterial organs are located. In order to protect one of the most vital regions in the body, the body has developed an impressive array of defenses. The bones are one of the most significant protections of the body. 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. Every bone in the body has a slightly different shape and size, which is controlled by the genetic code. Protection, support, and shape are some of the significant importance’s of the skeletal bones.
Another key function of the bone that most people neglect or fail to realize is the production of red and white blood cells. In the center of most bones lies a substance known as bone marrow. In this region, red blood cells and white blood cells are produced. These red blood cells are essential for survival of the body, this is because these cells carry oxygen to other cells. 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 thorax, twenty five bones can be found. 24 of these bones are known as the rib, and the body contains 2 sets of 12 ribs on each side of the chest. Along with the ribs, one sternum bone can be found. All 25 of these bones play vital roles in protecting the organs of the chest, such as the lungs and heart. 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.
Humans would find it very difficult to survive without the protection of the thorax bones. It would be very easy to damage organs such as the heart or lungs. 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.
