It is a peculiarity of mammalian red blood cells (RBCs) that the nucleus is extruded (pushed out of the cell) as the cell develops. Other organelles, including mitochondria, are also lost.
Without a nucleus, the cell lacks genetic control over its activities. This probably explains why RBCs are broken down after a relatively short time.
In humans, the average life of an RBC is about 120 days. We make about three million new ones every second.

How red blood cells get replaced?
Red blood cells are constantly being replaced in the bone marrow through a process called erythropoiesis. This process is controlled by the hormone erythropoietin, which signals the bone marrow to produce more red blood cells when levels are low. Old or damaged red blood cells are removed by the spleen and liver.
Do you lose red blood cells?
Yes, red blood cells have a limited lifespan of about 120 days and are constantly being broken down and replaced by the body. This turnover of red blood cells is essential for maintaining a healthy blood supply.
How long does it take for all of the red blood cells in your body to be replaced 10 times?
Red blood cells have a lifespan of about 120 days. If it takes about 120 days for all red blood cells to be replaced once, then it would take approximately 1200 days (120 days x 10) for them to be replaced 10 times in your body. This is roughly equivalent to 3.3 years.
What does the replacement of red blood cell depend mostly on?
The replacement of red blood cells primarily depends on the rate of production in the bone marrow and the lifespan of the cells. Red blood cells normally have a lifespan of about 120 days, after which they are removed from circulation and replaced with new ones. The body closely regulates the production of red blood cells to maintain a stable level of oxygen-carrying capacity in the blood.
How do your body generate blood after donating?
After donating blood, red blood cells are replaced by bone marrow, but usually takes a month to be fully replaced, but it can also take longer depending on how frequently the donor donates blood.
What Blood Cells are replaced on a regular basis?
the red blood cells are

How long for all of the red blood cells in your body to be replaced.?
red blood cells are replaced ever 120 days, so therefore are replaced 3 times a year
What percentage of adult red blood cells are replaced daily?
Approximately 1% of adult red blood cells are replaced daily in the human body. This turnover ensures a constant supply of fresh and functional red blood cells to carry oxygen to tissues and organs.
What part of the blood is replaced every 3-4 months?
Red blood cells
Do you lose red blood cells?
Yes, red blood cells have a limited lifespan of about 120 days and are constantly being broken down and replaced by the body. This turnover of red blood cells is essential for maintaining a healthy blood supply.
What would happen if you lost a few red blood cells?
One loses 'a few red blood cells' every minute. They wear out, or bleed out, etc., and are replaced.
Red blood cells need to be replaced every how many days?
40 to 50

What are the the cells that carry oxygen?
Red blood cells contain hemoglobin. These cells are also known as erythrocytes.
