What's Inside a Bone?

   Your bones are alive and have living cells growing inside of them.  Bone cells are called Osteocytes.  They take in food and give out waste.  There constantly need repair.  Bones are made 45% minerals/Calcium Phosphate.  Which gives bones there hardness.  Also bones are filled with red and yellow jelly stuff in them... this stuff is called marrow.  The yellow marrow stores fat and releases it when it is needed else where.  But the red marrow is tissue that make red and white blood and white blood cells in big amounts.   Your body produces at least 5,000 white and red blood cells every day. Your bone is like a microscopic honey comb with tons of spaces for blood cells and nerves to get.   That is about all you need to know that is until you become some super smart scientist.
