Question

5. What is the size of a human blood cell and what are the benefits of this size?​

Answer 1

Explanation:

Normal RBCs have a diameter of 6 - 8 μm. On a peripheral blood smear, normal RBCs are disc-shaped with a pale-staining central area called the central pallor. When judging red cell size on a blood smear, the classic rule of thumb is to compare them to the

nucleus of a small normal lymphocyte.

Normal human red blood cells (MCV 95 cu mu) increased platelet adherence sevenfold, as the hematocrit increases from 0 to 0.6. ... These data indicate that red cell size is of major importance for platelet adherence. Red cell diameter is more important than average volume.

Answer 2

A red blood cell is 0.000007 of a meter in size.
