The chest is one of the most significant locations in the human body. 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, not many people know the structure of these bones. 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.
Although the bones play essential roles in protection, another vital function of the bones are creation of white and red 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.
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. These chest bones are essential in the protection of 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. 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. The thorax bones are responsible for 25 out of 206 bones in the human body skeleton.
