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. The body has developed a series of defenses to protect one of the most significant regions in the body. 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. Bones are made up a type of dense connective tissue, formed from deposits of calcium phosphate.. Every bone in the body has a slightly different shape and size, which is controlled by the genetic code. The skeletal bones are very important in aiding the body with movement and strength.
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. In this bone marrow region, the red and white blood cells are formed. These red blood cells are essential for survival of the body, this is because these cells carry oxygen to other cells. 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 thorax contains twenty four ribs out of the total twenty five bones in the chest. The other bone of the chest is the sternum. All of the thorax bones play important functions in protecting the chest organs. The twenty four ribs are curvy 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.
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. Since evolution drives organisms to survive, humans have evolved to develop these thorax bones to protect the lungs and heart. The thorax bones are responsible for 25 out of 206 bones in the human body skeleton.
