Life cycle.
Human red blood cells are produced through a process named erythropoiesis, developing from committed stem cells to mature red blood cells in about 7 days. When matured, in a healthy individual these cells live in blood circulation for about 100 to 120 days (and 80 to 90 days in a full term infant).

Life span of RBC and WBC:
The life span of red blood cells (RBC) and white blood cells (WBC) varies significantly, with RBCs living much longer than WBCs.
RBC:
- The life span of a red blood cell is around 120 days.
- RBCs are constantly being produced by the bone marrow to replace the old cells that are removed from circulation by the spleen and liver.
- After about 120 days, RBCs become old and are removed from circulation, making room for new RBCs.
WBC:
- The life span of a white blood cell can range from 6 to 20 days, depending on the type of WBC.
- White blood cells play a crucial role in the body's immune response and defense against infections.
- Different types of WBCs have different life spans, with some living only a few days while others can live for a couple of weeks.
Comparison:
- RBCs have a longer life span compared to WBCs because RBCs do not have a nucleus and other organelles, which enables them to live longer.
- WBCs, on the other hand, are more complex cells with a nucleus and organelles, which contribute to their shorter life span.
In conclusion, the life span of RBCs is around 120 days, while the life span of WBCs can range from 6 to 20 days, depending on the type of white blood cell.
