The contents of the blood enable your body to make an estimated three billion new cells every minute. The growth of hair is a result of cells multiplying at the root. As old skin flakes off your body, new skin cells multiply beneath. As cells are scraped off the walls of your intestines, new cells are made to replace them. Every second, millions of red blood cells are made in your bone marrow!
