Thorax bones and scapula anatomy go hand in hand
The chest is one of the most important regions in your body and for good reason too. The chest houses your lungs, heart, and vital arteries that carry blood to the rest of your body. The human body has created a strong system of defense to protect the chest region. 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. The bones are formed from calcium phosphate and a type of dense connective tissue. Every bone in the body has a slightly different shape and size, which is controlled by the genetic code. The bones of the body function in protecting the body and providing the body’s shape.
Another key function of the bone that most people neglect or fail to realize is the production of red and white blood cells. The bone marrow is located in the center of many bones in the skeleton. Red blood cells and white blood cells are produced in this region. 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 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. Along with the ribs, one sternum bone can be found. All of the thorax bones play important functions in protecting the chest organs. 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. While the ribs form a cage around the vital organs, the sternum is found in the middle of chest.
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. 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.
