So we have more of these red blood cells than our platelets. Now, just like these red blood cells, platelets also do not have any nuclei. But they are smaller than these red blood cells and they have other organelles. Now, our platelets actually function in the blood clotting process. So they travel along our blood vessels until they come to a cut or a hole in the lithium of our blood vessel. And then they stick to that hole and they initiate a process.
