Q. The average diameter of red blood corpuscles of man is
A) $7.2\ \mu\ m$
B) $8.1\ \mu\ m$
C) $9.2\ \mu\ m$
D) $10.3\ \mu\ m$
Explanation
In mammals, $RBC_{S}$ are roughly circular, biconcave, disc like, non-nucleated corpuscles. In human, the$\ RBC_{S}$ are$\ 6.5\ \mu\ to\ 8\ \mu$ in diameter (average diameter$\ 7.2\ \mu$) and $1 - 2\ \mu$ thick.
