You may have seen an image of a red blood cell (RBC) in the past: it is a small, pink disc, lighter in color in the center than around the sides. It looks lighter in the center because the cell is thinner there, allowing more light to pass through. However, red blood cells can come in many shapes and sizes besides the familiar disc.
