Many scientists would agree that the chest is perhaps the most vital region in the entire human body. In this chest region, organs essential to survival, such as the lungs, heart, and arteries, are located. The human body has created a strong system of defense to protect the chest region. One of the most important defense that the body created is 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 few know their structure and composition. The bones are created from a special type of tissue, known as dense connective tissue.. Every bone in the body has a slightly different shape and size, which is controlled by the genetic code. The bones of the body function in protecting the body and providing the body’s shape.
Another key function of the bone that most people neglect or fail to realize is the production of red and white blood cells. A soft region, known as the bone marrow, is located at the center of many skeletal bones. Red blood cells, also known as RBC’s, and white blood cells, also known as WBC’s, are produced in this bone marrow region. These red blood cells are very significant for the body’s function because the carry oxygen to cells in the body. White blood cells are part of the immune system and play important roles in defending against bacteria.
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. A relatively long bone known as the sternum is also found in the thorax. 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. Along with protecting the heart and lungs, the ribs allow breathing by expanding and compressing. 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. The lack of the chest bones would allow the easy damage of the circulatory and respiratory organs. Therefore, in order to protect itself, the body has devised these bones to defend the organs. Of all two hundred six bones in the body, the chest bones make up twenty five bones.
