Can red blood cells divide if is lost?

No, red blood cells cannot divide if their nucleus is lost. In fact, red blood cells do not have a nucleus, so they cannot divide at all. They are the only cells in the human body that do not have a nucleus.

Red blood cells are produced in the bone marrow, and they are released into the bloodstream when they are mature. They have a lifespan of about 120 days, after which they are destroyed by the spleen and liver.

Because they do not have a nucleus, red blood cells cannot repair themselves if they are damaged. This is why it is important to take care of your health and protect your red blood cells from damage.
