The chest, also known as the thorax, is a very significant part of the 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. 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. 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.

Although the bones play essential roles in protection, another vital function of the bones are creation of white and red blood cells. A soft region, known as the bone marrow, is located at the center of many skeletal bones. In this bone marrow region, the red and white blood cells are formed. 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 part of the immune system and play important roles in defending against bacteria.

Twenty five skeletal bones are found in the chest region. 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. These twenty five thorax bones are very significant in protecting the organs of the respiratory and circulatory system. The ribs are curved skeletal bones that form a structure known as the rib cage around the lungs and heart. 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.

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. 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.
