Bones, Bones, Bones!
Bones are what keep us from being a giant blob of skin, muscle, and organs. There is an average of 206 bones in the adult human body. Bones store minerals and they also make red and white blood cells. Bone is a very important organ, did you know that it grows?
Bones are made from connective tissue as well as minerals. Osteoblast cells drop off minerals into the bones. There are two different types of bone tissue, spongy bone, and compact bone. Compact bone is the outside of the bone, the dense stuff. Spongy bone is the inside. It holds the most strength on keeping you upright.
There are two other types of tissues in the bones, yellow marrow, and red marrow. Yellow marrow stores fat, and red marrow makes blood cells. Yellow marrow is only found in the center most part of the femur.
Bones grow at a pretty fast pace while we are babies, and then slows when we hit puberty. After a while of small growth spurts, you stop growing altogether. When we are born, we have a soft spot on our skull, this is so the baby can pass its way through the birth canal. When you are born, not only is your skull made of cartilage, almost your whole skeletal system is.
There isn't as much true bone when you are born, but cartilage is replaced with true bone as we are growing. This is the way we grow, we replace growth plates or cartilage with bone. Cartilage is what makes our ears, and the tip of our nose.
