    Re: measuring the size of red and white blood cells.

    did you use grids to measure the field of view? but since you said you've done the prac i'll just assume you did and give you the results:

    Red blood cells should be about 7 micometres (in diametre) and white blood cells should be around 10-12 micrometers (in diametre).

    HI,

    Measuring of the red blood cells,In humans, mature red blood cells are flexible biconcave disks that lack aand most The cells develop in thand circulate for about 100-120 days in the body before their components are recycled by Each circulation takes about 20 seconds. Approximately a quarter of the cells in the human body are red blood cells.



    Thank you....

    Re: measuring the size of red and white blood cells.

    Estimated diameter of small (400x) field of view: 0.45mm
    Estimated number of red blood cells (400x): 53
    Estimated size (diameter) of a red blood cell: 0.45mm/53 = 8.5 x 10-3 mm x 1000 = 8.5 micrometers

    This is just an example of results. Your results may vary slightly, however the method stays the same, use the size of the mini-grid/field of view to calculate the RBC size.
