Many scientists would agree that the chest is perhaps the most vital region in the entire human body. Inside the chest, the heart, lung, and arterial organs are located. The human body has created a strong system of defense to protect the chest region. One of the most important defense that the body created is 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, not many people know the structure of these bones. 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 key function of the bones that is often overlooked 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. Red blood cells are very important in that they carry oxygen to other cells in 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 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 slightly curved bones that form a cage across the chest. The rib skeletal bones also allow breathing by contracting and expanding the chest. 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. It would be very easy to damage organs such as the heart or lungs. Therefore, in order to protect itself, the body has devised these bones to defend the organs. Of all two hundred six bones in the body, the chest bones make up twenty five bones.
