1000 red blood cells
To 1 white blood cell
white cells are twice as large as red cells
RBC = 70 percent
Around 700:1
a microscope measures the size of an object (example: how big an blood cell is)
no, the smallest cell ever is your white blood cells, they defend your body from all sorts of diseases, from cancer to dimenture. They are one millionth of a centimetre. If you are talking about the smallest cell in the world, then it is actually a virus, it is about one millionth of a millimetre
While they are very similar in size white blood cells are bigger while red bloods cells are much more numerous.
Red Blood Cell = 8 micrometers Sperm Cell = 60x5 micrometers Skin Cell = 30 micrometers Egg Cell = 130 micrometers Information obtained from (where there's a dandy to-scale, zoomable picture): http://learn.genetics.utah.edu/content/begin/cells/scale/
White Blood Cell Count (WBC) 4,300 - 10,800 cells/µL/cu mm The above is norm - i.e. 4.3 to 10.8 Therefore 3.0 is slightly on the low side - BUT not majorly low - this figure can vary due to size weight and a large set of variables. Only your GP or MD will be able to answer this question correctly for you.
10 to 100 microns
The size of a white blood cell is on average about 700 times smaller than a red blood cell. Source: http://library.thinkquest.org/25896/sub_blood/wbc.htm
15 micro meters
much smaller than a eukaryotic cell.
wouldn't have a clue.. sorry boss
White blood cells are larger. White blood cells range in size from 7-21 micrometers in diameter. Red blood cells are typically 6-8 micrometers in diameter. However, RBCs are more prevalent, accounting for 25% of the volume of blood, whereas WBC's only account for 1%.
Blood cell is 20 micrometers, and a dute mite is 200 micrometers

the average size of a red blood cell is about 7.2 micrometers in diameter.
It is 8µm in size.
They are 6-8 micrometres
15 micrometers
