The chest is one of the most significant locations in the human body. In this chest region, organs essential to survival, such as the lungs, heart, and arteries, are located. In order to protect one of the most vital regions in the body, the body has developed an impressive array of defenses. 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, not many people know the structure of these bones. The skeletal bones are created primarily from calcium phosphate that creates 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.

Although the bones play essential roles in protection, another vital function of the bones are creation of white and red blood cells. The bone marrow is located in the center of many bones in the skeleton. Red blood cells, also known as RBC’s, and white blood cells, also known as WBC’s, are produced in this bone marrow region. 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. The thorax contains twenty four ribs out of the total twenty five bones in the chest. Along with the ribs, one sternum bone can be found. These twenty five thorax bones are very significant in protecting the organs of the respiratory and circulatory system. 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.

Humans would find it very difficult to survive without the protection of the thorax bones. Without these bones, vital organs such as the heart and lungs could be compromised. 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.
