The chest is one of the most significant locations in the 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 The human skeleton bones are one of the top defenses of the body.
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. The bones of the skeletal system all have distinct shapes and sizes. The bones of the body function in protecting the body and providing the body’s shape.
Although the bones play essential roles in protection, another vital function of the bones are creation of white and red blood cells. The bone marrow is located in the the center of many bones in the skeleton. Red blood cells and white blood cells are produced in this region. Red blood cells are very important in that they carry oxygen to other cells in the body. White blood cells are very important in that they defend the body against invaders and pathogens.
In the chest, there are 25 bones. 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 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. Therefore, in order to protect itself, the body has devised these bones to defend the organs. The chest bones account for a total of 25 bones out of the 206 bones in the human skeleton.
