    White cells are larger than red blood cells and can be larger than the diameter of a capillary, so must deform to fit. As a large, deformed white blood cell goes through a capillary, a space opens up in front of it and red blood cells pile up behind. This makes the dots of light appear slightly elongated with dark tails.

    To obtain the pattern for the database record, an individual inserts a finger into an attester terminal containing a near-infrared light-emitting diode (LED) light and a monochrome charge-coupled device (CCD) camera.

  9. Venous blood - Wikipedia

    en.wikipedia.org/wiki/Venous_blood

    Though veins might make it appear as such, human blood is never naturally blue. [3] The blue appearance of surface veins is caused mostly by the scattering of blue light away from the outside of venous tissue if the vein is at 0.5 mm deep or more. Veins and arteries appear similar when skin is removed and are seen directly. [4] [5]
