Many scientists would agree that the chest is perhaps the most vital region in the entire human body. The chest houses your lungs,
heart, and vital arteries that carry blood to the rest of your body. In order to protect one of the most vital regions in the body, the body has developed an impressive array of defenses. The human skeleton bones are one of the top defenses 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. Each bone has a unique shape, determined by the genetic code that leads to the formation of the bones. Protection, support, and shape are some of the significant importance’s of the skeletal bones.
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 bone marrow region, the red and white blood cells are formed. Red blood cells are very important in that they carry oxygen to other cells in the body. White blood cells are very important in that they defend the body against invaders and pathogens.
In the chest, there are 25 bones. Of all the bones in the chest, twenty four of these bones are known as the ribs. The body contains two sets of ribs on each side of 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 slightly curved bones that form a cage across the chest. The rib skeletal bones also allow breathing by contracting and expanding the chest. While the ribs form a cage around the vital organs, the sternum is found in the middle of chest.
These chest bones play an essential role in human survival and existence. 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. Of all two hundred six bones in the body, the chest bones make up twenty five bones.
