The chest is one of the most significant locations in the human body. The chest houses your lungs, heart, and vital arteries that carry blood to the rest of your body. The human body has created a strong system of defense to protect the chest region. 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, not many people know the structure of these bones. The skeletal bones are created primarily from calcium phosphate that creates connective tissue. The bones are formed from calcium phosphate and a type of dense connective tissue. The bones of the skeletal system all have distinct shapes and sizes. 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. 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. Red blood cells are very important in that they carry oxygen to other cells in the body. White blood cells are part of the immune system and play important roles in defending against bacteria.

Twenty five skeletal bones are found in the chest region. 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. A relatively long bone known as the sternum is also found in the thorax. These twenty five thorax bones are very significant in protecting the organs of the respiratory and circulatory system. The ribs are curved skeletal bones that form a structure known as the rib cage around the lungs and heart. These bones protect the heart and lungs and also expand to allow for breathing. 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. The lack of the chest bones would allow the easy damage of the circulatory and respiratory organs. 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.
