how many blood cells do you have in your body?

Answer 1

This will vary from person to person with their size and state of health.

Wikipedia says:
Adult humans have roughly 2–3 × 10^13 red blood cells at any given time

Answer 2

"Adult humans have roughly 2–3 × 10^13 red blood cells at any given time"

"There are normally between 4 × 10^9 and 1.1 × 10^10 white blood cells in a litre of blood "
(The average adult has a blood volume of about 5 litres).
So total white blood cells would be between 20 x 10^9 and 5.5 x 10^10.

So
20,000,000,000,000 to 30,000,000,000,000
for red.

and
20,000,000,000 to 55,000,000,000
for white.


So a total minimum of:
20,020,000,000,000 blood cells.
and a total maximum of:
30,055,000,000,000 blood cells

Answer 3

There are many different types of blood cells. Erythrocytes (red blood cells), neutrophils, macrophages, lymphocytes, plasma cells, basophils, mast cells, eosinophils (all white blood cells). You have different amounts of each type.
