In 1cm3 of blood, there are 5,000,000,000 red blood cells and 8,000,000 white blood cells. Meaning a ratio of 5000 to 8.

in any given mm3 of blood, what is the approximate ratio of the number of red blood cells (erythrocytes) to white blood cells (leukocytes)
Ther are equal numbers of red and white
Yes they are called erethrocytes
There are approx. 7,000 leukocytes per cubic millimeter of blood.
Mononucleosis
Leukopenia
Lymphocytes are the "agranulocytes" in larger number in blood.
White blood cells (leukocytes)
erythrocytes Erythrocytes
There are about a thousand times as many red blood cells as white cells. Consider that the red blood cells (or erythrocytes) in a mm3 (or microliter) of blood number about five million in an average man (a few less in a woman). The white blood cells (or leukocytes) number only 5-6 thousand per mm3 so the ratio is about a thousand fold.
The common name for leukocytes is white blood cells.
