When a human donor gives a pint of blood, how many weeks are required for the body RESERVE of red corpuscles to be replaced?

  • A.1 week
  • B.3 week
  • C.7 week
  • D.21 week

Answer: C

About 7 weeks are needed to replace the body's reserve of red corpuscles after giving a pint of blood.

The plasma volume is restored within a day or two, and the red cell count within a few weeks, but the iron stores that back it up take considerably longer - which is why donors are asked to wait about three months.
