White blood cells (also called leukocytes) are fewer in number than red blood cells, with a ratio of about 1 white blood cell to every 600 to 700 red blood cells . White blood cells are responsible primarily for defending the body against infection. There are five main types of white blood cells.
How many white blood cells are in each red blood cell?
RBCs account for approximately 40 to 45 percent of the blood. This percentage of blood made up of RBCs is a frequently measured number and is called the hematocrit. The ratio of cells in normal blood is 600 RBCs for each white blood cell and 40 platelets.

Why low white blood cell count is bad?
The main risk of an abnormally low white blood cell count is how vulnerable it may make a person to infection . Without an adequate white blood cell response available to fight infection, the body is at greater risk that any infection (including those usually regarded as minor) may cause serious illness or death.
