            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. The human body has created a strong system of defense to protect the chest region The human skeleton bones are one of the top defenses of the body.

            Many people know what the skeletal system bones look like. However few know their structure and composition. The bones are created from a special type of tissue, known as dense connective tissue. 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. The skeletal bones are very important in aiding the body with movement and strength.

             One of the most important functions Is the production of red blood cells and white blood cells. In the center of most bones lies a substance known as bone marrow. 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 part of the immune system and play important roles in defending against bacteria.

             In the thorax, twenty five bones can be found. 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. 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. These bones protect the heart and lungs and also expand to allow for breathing. The other bone of the chest, the sternum, is found in the center of the chest. It’s role is protection of the heart primarily.

            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. Therefore, in order to protect itself, the body has devised these bones to defend the organs. The chest bones account for a total of 25 bones out of the 206 bones in the human skeleton.
