Some Properties of Human Blood Components

Component Concentration (#/mL) Size (µm) Density (g/mL) Comments Ref
Red blood cell 4.0–5.7 × 109 6.2–8.2 1.086–1.122 Usually enucleate; generally no
DNA; flexible biconcave discoid
shape.		 40
White blood cell 4–11 × 106 7–30 1.057-1.092 DNA in every cell; spherical
with many different sizes;
monocytes can be as large as
30 µm.		 41,42
Platelets 1.3–4.0 × 108 2.0–4.0 1.072–1.077 No DNA; easily activated to
aggregate and adhere to surfaces;
biconcave discoid when
not activated.		 41
Plasma – – 1.024 Contains high concentrations of
proteins and other
