For example, we have monocides, we have lymphocytes, and we also have mast cells and other leukocyte types. Now, let's move on to our Thrombicides, also known as platelets. Now, the ratio of Thrombocides to red blood cells in our blood is about one to ten. 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.
