They only have 120 days of lifespan. It is not long.

But rbc don't do any metabolic processes. They passively move around.

i believe liposomes entrap hb to make an rbc that how it is made artificially. therefore it does not require a nucleus.

oxygen would oxidize the rbc and shorten it's life.

wbc play an important role in your body for immunity.life spans of wbc are various.neutrophil who phagocytoses cells or bacterias stays for 8h in blood circulation when produced then transits into the tissue 3~5d later they will die...
