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.
No they don't. They last about 3-4 months for a healthy person. The cells that line your stomach/GI system have much shorter life span.
Accually,a red blood cell for a a week. Plus more blood cells are made than died most of the time
The red blood cells are like every other living thing. They have a life span. When they're used for a certain amount of time they get worn out. i guess that's why.
Yes erythrocytes have the life span of 120 days.
Red blood cells get replaced because eventually they wear out and are removed from circulation. If they were not replaced, the person would become anemic and eventually die.
All cells age. Red blood cells are particularly prone to aging because they have no nucleus when mature.
The old red blood cells get replaced by the newly formed red blood cells.
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.

Red blood cells contain hemoglobin, but white blood cells do not
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.
The old red blood cells get replaced by the newly formed red blood cells.
the red blood cells are
red blood cells are replaced ever 120 days, so therefore are replaced 3 times a year

One loses 'a few red blood cells' every minute. They wear out, or bleed out, etc., and are replaced.

Red blood cells contain hemoglobin. These cells are also known as erythrocytes.
Red blood cells because that is what carries oxygen throughout the body
