Question

R. B. C. का जीवन काल कितना है?

Answer 1

A process called erythropoiesis is responsible for the production of red blood cells taking about 7 days to be mature enough for circulation and circulate for around 100 to 120 days.

After these days, the cells are removed from circulation.

So, the lifespan of red blood cells is around 100-120 days.
