The chest is one of the most important regions in your body – and for good reason too. In this chest region, organs essential to survival, such as the lungs, heart, and arteries, are located. 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.
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. Every bone in the body has a slightly different shape and size, which is controlled by the genetic code. The bones play essential roles in movement, support, strength, protection, and shape.
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. Red blood cells and white blood cells are produced in this region. These red blood cells are essential for survival of the body, this is because these cells carry oxygen to other cells. White blood cells are part of the immune system and play important roles in defending against bacteria.
In the chest, there are 25 bones. 24 of these bones are known as the rib, and the body contains 2 sets of 12 ribs on each side of the chest. The sternum is the 25th bone of the chest that accompanies the twenty four rib bones. These chest bones are essential in the protection of the lungs and heart. 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 other bone of the chest, the sternum, is found in the center of the chest. It’s role is protection of the heart primarily.
Without these chest bones, human existence would be greatly compromised. 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 thorax bones are responsible for 25 out of 206 bones in the human body skeleton.
