How do red blood cells multiply?

Answer 1

Mature red blood cells are not capable of dividing, as they do not possess nuclei. Therefore, it is not possible that red blood cells will divide as they travel along our blood vessels. New red blood cells are produced in the red bone marrow of long bones in adults, not from the cell division of mature red blood cells.

"RBCs are terminally differentiated; that is, they can never divide. They live about 120 days and then are ingested by phagocytic cells in the liver and spleen."

Answer 2

they duplicate and i think a mixture of oxygen and protein helps it to grow. hope this helps x

Red blood cells are produced in the bone marrow, the femur being the largest bone, therefore makes the most red blood cells. They are stored in the spleen, released into the bloodstream, last for 22 days, and then are destroyed by the liver.

I'm not saying the answer given at the top of this is wrong, all cells grow by using oxygen and proteins, and red blood cells are what are called 'daughter cells'.

Answer 3

Red blood cells cannot divide, because they don't have a nucleus. Instead, RBCs are continuously manufactured in the bone marrow.

Answer 4

Red blood cells are not complete cells, they do not have a nucleus and cannot divide. They are produced by specialized tissue in the bone marrow.

Answer 5

I don't know; use a website that's actually reliable instead of this one.

Answer 6

They cannot. Red blood cells do not contain a nucleus, which means they are not able to replicate. Instead they must be constantly manufactured in the bone marrow.
