The chest is one of the most significant locations in the human body. The thorax is home to critical organs in the body, such as the heart, lungs, and aorta. 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. 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. Protection, support, and shape are some of the significant importance’s of the skeletal bones.
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. These red blood cells are very significant for the body’s function because the carry oxygen to cells in the body. The white blood cells are also very important for bodily function because these cells play a role in defending the body from pathogens.
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 twenty five thorax bones are very significant in protecting the organs of the respiratory and circulatory system. The ribs are slightly curved bones that form a cage across the chest. The rib skeletal bones also allow breathing by contracting
and expanding the chest. 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. Since evolution drives organisms to survive, humans have evolved to develop these thorax bones to protect the lungs and heart. The chest bones account for a total of 25 bones out of the 206 bones in the human skeleton.
