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. 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, not many people know the structure of these bones. The bones are formed from calcium phosphate and a type of dense connective tissue. The bones of the skeletal system all have distinct shapes and sizes. 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 region, red blood cells and white blood cells are produced. 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 thorax contains twenty four ribs out of the total twenty five 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 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. Without these bones, vital organs such as the heart and lungs could be compromised. Thus through evolution, the body has developed these defense mechanisms to protect the vital organs. The thorax bones are responsible for 25 out of 206 bones in the human body skeleton.
