Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33×10−6 m and 0.0000075 m, respectively. Which blood component has a bigger diameter, and approximately by how much?
The red blood cell has a bigger diameter, approximately by:
Diameter of red blood cell - Diameter of platelet
= (0.0000075 m) - (2.33×10^-6 m)
= 5.17×10^-6 m
