The chest, also known as the thorax, is a very significant part of the human body. The thorax is home to critical organs in the body, such as the heart, lungs, and aorta. 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. 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. Protection, support, and shape are some of the significant importance’s of the skeletal bones.
One of the most important functions Is the production of red blood cells and white blood cells. The bone marrow is located in the center of many bones in the skeleton. Red blood cells, also known as RBC’s, and white blood cells, also known as WBC’s, are produced in this bone marrow region. 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 very important in that they defend the body against invaders and 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. Along with the ribs, one sternum bone can be found. These twenty five thorax bones are very significant in protecting the organs of the respiratory and circulatory system. The twenty four ribs are curvy 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. 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. Of all two hundred six bones in the body, the chest bones make up twenty five bones.
