The state of a red platelet is a biconcave circle with a straightened focus - as it were, the two essences of the circle have shallow bowl-like spaces (a red platelet resembles a doughnut).

Blood seems red as a result of the huge number of red platelets, which get their shading from the hemoglobin. The level of entire blood volume that is comprised of red platelets is known as the hematocrit and is a typical proportion of red platelet levels.
