Bones

There are a total of approximately 206 bones in the human body making up a very important structure in the body that performs five essential functions. The bones provide shape, protection, movement, red blood cell production, and mineral storage. While the bones give our bodies shape they also support our body and contain enough strength to support our entire weight. They provide protection acting as cushioning for our internal organs, particularly if we fall. The skull protects our brain, and the rib cage helps to protect the heart, liver, lungs and the spleen. The pelvis helps to protect the bladder, intestines and reproductive organs. Because bones are attached to muscles they provide a variety of movements for the body making ambulation, work and play possible. Bone marrow located within the inner structure of the bone has the ability to make red blood cells. Red blood cells circulate with in the blood stream carrying oxygen from the lungs to each body tissue and they are a key player in getting the waste carbon monoxide to the lungs where it can be breathed out. The last function is mineral storage. The minerals that are stored are calcium and phosphate which can be utilized by the body when it is necessary. Calcium is used in the body to make our bones stronger so they don’t become brittle. Phosphate is used to help repair the bones and teeth, contribute to nerve function and help the muscles contract. The human skeletal system has many talents and is a vital player in maintaining homeostasis.
