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 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 few know their structure and composition. Bones are made up a type of dense connective tissue, formed from deposits of calcium phosphate. 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. The skeletal bones are very important in aiding the body with movement and strength.

One of the most important functions Is the production of red blood cells and white blood cells. In the center of most bones lies a substance known as bone marrow. Red blood cells and white blood cells are produced in this region. The red blood cells are very important because they transport O2, also known as oxygen, to all regions of the body. White blood cells are very important in that they defend the body against invaders and pathogens.

In the thorax, twenty five bones can be found. The ribs make up the majority of the bones found in the chest. There are twenty four rib bones in the chest. The other bone of the chest is the sternum. All 25 of these bones play vital roles in protecting the organs of the chest, such as the lungs and heart. 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. The sternum lies at the center of the chest, protecting the heart.

Without these chest bones, human existence would be greatly compromised. The lack of the chest bones would allow the easy damage of the circulatory and respiratory organs. Thus through evolution, the body has developed these defense mechanisms to protect the vital organs. Of all two hundred six bones in the body, the chest bones make up twenty five bones.
