The skeletal system is one of the most important systems in the human anatomy. Without this system our bodies wouldn’t have any source of motion or movement. From the skull all the way to the toes of our feet, everything is important. Out of the 206 bones, they all form our different shapes and make us all unique. They create our framework and enables us the move and perform our different activities during our everyday life. Another thing that the skeletal system does is protects all of our vital organs. It also produces blood cells; the marrow in some bones produces these. 2.6 million Blood cells are produced a second. These blood cells are used to carry oxygen to and from your lungs. Without oxygen, well you’d die in a matter of 20 minutes. Another fact to consider is that bones also serve as a storage area. ("Skeletal System.")
The Skeleton also protects the human body from injuries. It does this by protecting fragile areas such as the rib cage for your heart and lungs, the skull for your brain, and the vertebrae is made up to protect your spinal cord. Not only is the skeletal system fragile, but it also contains a lot of calcium, which is of major importance to the human body. It’s impressive how our bones have more calcium than any other organ in the human body. The largest amounts of calcium salts can be found in the intercellular matrix of bone. The most important, though, is called calcium phosphate and without it we wouldn’t grow. Neither would our blood cells, or tissues. A great thing about calcium in the bones is that it doesn’t just help people stay healthy; it’s a more advanced process. It starts off when your blood runs low on producing calcium, which isn’t normal, and then your bones give off the amount of calcium that your metabolism needs. When the amount of calcium increases in your blood, then the extra calcium gets saved in the
