The chest is one of the most important regions in your body and for good reason too. In this thorax region, the organs of the circulatory system and respiratory system are housed. In order to protect one of the most vital regions in the body, the body has developed an impressive array of defenses. 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 bones play essential roles in movement, support, strength, protection, and shape.

One of the most important functions Is the production of red blood cells and white blood cells. In the middle region of many bones exists the bone marrow. 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 part of the immune system and play important roles in defending against bacteria.

In the chest, there are 25 bones. The thorax contains twenty four ribs out of the total twenty five bones in the chest. The sternum is the 25th bone of the chest that accompanies the twenty four rib bones. 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. 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. 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.
