When you think of your bones you probably imagine them as the hard, white things in your body that keep you upright. But have you ever thought about what your bones are made up of?
Our bones are so much more complex than you can imagine. Each bone is made up of an intricate matrix of collagen, calcium, and phosphorus. We also have thousands of cells and nerves inside of our bones. This is why we feel pain if we hurt or damage the bone.
You have probably heard the words ‘bone marrow’ before, but I doubt you truly understand what it is. I am sure you can imagine how crucial bone marrow can be to our bones from the name. Bone marrow is found in long and flat bones like our shoulders, hips, and ribs. There are two types of bone marrow in our bodies: red marrow and yellow marrow.
Red marrow creates red blood and stem cells, which can be made into osteoblasts. Osteoblasts are ‘immature’ bone cells that help create the minerals our bones are made out of.
Yellow marrow is mostly made of fat cells and do not do much. Their only job is to support the red marrow’s activity. Something interesting to take note of is the yellow marrow’s ability to turn into red marrow. If you have a serious injury, like a gun wound, and you lose a lot of blood, the yellow marrow will convert itself into red marrow to create more red blood cells to help make up for the loss of blood.
As you can see, bone marrow is a really interesting and crucial part of our bones. Like many children my age, I have heard the term before on TV shows, but I have never considered what it may be and why it is important. The human body never ceases to amaze me with how important every little cell and fluid is to our everyday functioning.
