The chest, also known as the thorax, is a very significant part of the human body. In this thorax region, the organs of the circulatory system and respiratory system are housed. 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 few know their structure and composition. Bones are made up a type of dense connective tissue, formed from deposits of calcium phosphate.. The bones of the skeletal system all have distinct shapes and sizes. Protection, support, and shape are some of the significant importance’s of the skeletal bones.

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. The red blood cells are very important because they transport O2, also known as oxygen, to all regions of the body. White blood cells are very important in that they defend the body against invaders and pathogens.

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. The sternum is the other bone that makes up the chest. All 25 of these bones play vital roles in protecting the organs of the chest, such as the lungs and heart. The ribs are curved skeletal bones that form a structure known as the rib cage around the lungs and heart. Along with protecting the heart and lungs, the ribs allow breathing by expanding and compressing. While the ribs form a cage around the vital organs, the sternum is found in the middle of chest.

Without these chest bones, human existence would be greatly compromised. The lack of the chest bones would allow the easy damage of the circulatory and respiratory organs. 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.
