The Skeletal System
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 frame work 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. The heart and lungs wouldn’t be anything without our sternum and rib cage. That’s why when you break a rib it hurts to breathe. The rib you have broken keeps poking your lungs, and in some case can poke a hole in your lungs. 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. They store needed calcium and phosphorus. Without these minerals we wouldn’t grow. Neither would our blood cells, or tissues. So when we are born, that’s how small we would be for the rest of our life. Crazy isn’t it? There are many uses of the skeletal system. Different bones do different things and have different functions. The Spine, the ribs, and the femur are some of these many different bones. I think it’s about time I tell you about these, so that’s what I intend to do next. The Spine
The spine is one of the most (if not the most) important bones in the human body. It is the “back-bone” of the body if you will. It looks like a column of bone and cartilage that goes from the back of your head all the way to the pelvic region. The reason I say that it is probably the most important bone is the body is because it houses the spinal cord. The spinal cord sends signals to the different parts...
