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. The human body has created a strong system of defense to protect the chest region. 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, not many people know the structure of these bones. The bones are created from a special type of tissue, known as dense connective tissue.. Every bone in the body has a slightly different shape and size, which is controlled by the genetic code. The skeletal bones are very important in aiding the body with movement and strength.
One of the most important functions Is the production of red blood cells 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. 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. Along with the ribs, one sternum bone can be found. 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.
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. The thorax bones are responsible for 25 out of 206 bones in the human body skeleton.
