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. 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. 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. 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. In the middle region of many bones exists the 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. 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.
Twenty five skeletal bones are found in the chest region. The ribs make up the majority of the bones found in the chest. There are twenty four rib bones in 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 twenty four ribs are curvy bones that form a cage across the chest. These bones protect the heart and lungs and also expand to allow for breathing. While the ribs form a cage around the vital organs, the sternum is found in the middle of chest.
Humans would find it very difficult to survive without the protection of the thorax bones. 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.
