The chest is one of the most important regions in your body and for good reason too. 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. The bones are one of the most significant protections of the body. 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. The skeletal bones are very important in aiding the body with movement and strength.

One key function of the bones that is often overlooked is the production of red and white blood cells. In the center of most bones lies a substance known as bone marrow. In this bone marrow region, the red and white blood cells are formed. These red blood cells are essential for survival of the body, this is because these cells carry oxygen to other cells. The white blood cells are also very important for bodily function because these cells play a role in defending the body from pathogens.

In the chest, there are 25 bones. The thorax contains twenty four ribs out of the total twenty five bones in the chest. The sternum is the 25th bone of the chest that accompanies the twenty four rib bones. All 25 of these bones play vital roles in protecting the organs of the chest, such as the lungs and heart. 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 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. It would be very easy to damage organs such as the heart or lungs. Since evolution drives organisms to survive, humans have evolved to develop these thorax bones to protect the lungs and heart. Of all two hundred six bones in the body, the chest bones make up twenty five bones.
