Blood cells are predominantly red cells. They outnumber the white cells by a factor of 1000:1 to 2000:1 in normal humans.
The composition of blood is 55% plasma and 45% formed elements. The formed elements are mostly red blood cells, which make up 44% of total blood volume.
The remaining 1% consists of white blood cells and platelets.
Appx. 700:1
Blood consists of formed elements (red blood cells, white blood cells and platelets) and plasma. Red blood cells (erythrocytes) account for 99.9% of cells. Plasma 55%, and Cells 45%.

Leukocytes are among the formed elements of blood. They fight infection and identify and neutralize other "foreign" invaders. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
in any given mm3 of blood, what is the approximate ratio of the number of red blood cells (erythrocytes) to white blood cells (leukocytes)
Yes, there are typically many more erythrocytes (red blood cells) than leukocytes (white blood cells) in the blood. The ratio of red blood cells to white blood cells is about 600:1. This difference in numbers reflects the different functions and roles of these two types of blood cells in the body.
The three types of blood corpuscles are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Each plays a specific role in the body's immune response and oxygen transport.
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.
