We are going to check on it tomorrow and see if it has healed and clotted as our blood does when we graze ourselves.
Did you know in a pinhead size drop of blood there are 5,000,000 red blood cells, 10,000 white blood cells and 250,000 platelets? I wonder how many red blood cells there are altogether in your body?
