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. In order to protect one of the most vital regions in the body, the body has developed an impressive array of defenses. 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. Bones are made up a type of dense connective tissue, formed from deposits of calcium phosphate.. Each bone has a unique shape, determined by the genetic code that leads to the formation of the bones. The bones play essential roles in movement, support, strength, protection, and shape.
Another key function of the bone that most people neglect or fail to realize is the production of red 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. 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. Of all the bones in the chest, twenty four of these bones are known as the ribs. The body contains two sets of ribs on each side of the chest. The other bone of the chest is the sternum. These chest bones
are essential in the protection of the lungs and heart. The ribs are slightly curved bones that form a cage across the chest. 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.
Humans would find it very difficult to survive without the protection of the thorax bones. It would be very easy to damage organs such as the heart or lungs. 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.
