Bones are made of all sorts of stuff, marrow, collagen, and much more!
For example, there are 2 kinds of bone marrow, red and yellow. Yellow marrow produces fat cells, cartilage and bone. Red marrow produces blood cells.
Did you know that 70% Of your bones are not living tissue? They have their own blood vessels and they’re made of living cells. In the middle of your bones is a substance like a sponge. So it is soft on the inside and hard on the outside. If you drink milk your bones will become stronger. Did u know you have over 206 bones in your body?
Marrow, collagen are one of the most important things to the human body!
Question: did u know this?
Reflection: this took so long to do
