It does not have a nucleus to help it reproduce on its own, nor mitochondria that normally serves as an energy source for cells or other organelles to help maintain it. It is eventually broken down by the body and new RBCs are rebuilt in the bone marrow.
The life span of rbc is 4 month.
RBC have no nucleus. It is ejected as the cell develops so it can be packed with hemoglobin. Because of this it has a short life span of 120 days.

The same as a normal cat.
A red blood cell typically lasts about 120 days.
That depends on the region of the world that you refer to.
The normal life span of an emperor penguin is about 15 to 20 years. The emperor chicks may experience a 90 per cent mortality in the first year.
The normal RBC count in urine is - 4 RBC/HPF RBC -red blood corpuscle HPF - high power field
Females have a normal life to up to 75 Males have a normal life up to 71 but remember it is possible to live over your average life span

Normal lifespan is 15 to 25 years for a tiger.
