red blood cells in human do not have nucleus

The way red blood cells are produced is called erythropoiesis. They are produced in the bone marrow. They are constantly being produced. Normal maturation of a red cell is 7days, they then last about a total of 120 days. Their production is induced by a hormone called EPO (errythropoientin)

LIFE CYCLE OF THE ERYTHROCYTE
Every second 2.5 million RBC's are destroyed. Although this represents only 0.00001% of the total 25 trillion cells, these cells must be replaced if homeostasis is to be maintained.
Production of New RBC's - Erythropoiesis (takes 4 days)
1. Hemocytoblasts - Stem cells in the bone marrow from which all blood cells form.
2. Proerythroblasts - are produced by the division and differentiation of stem cells.
3. Basophilic (early) erythroblasts - During this stage in erythropoiesis hemoglobin synthesis begins.
4. Intermediate erythroblasts - At this time, we see the accumulation of hemoglobin due to its continued synthesis.
5. Late erythroblasts - During this stage the nucleus is extruded from the cell.
6. Reticulocyte - These cells exhibit a net-like appearance or reticulum in their cytoplasm when stained. A small number of reticulocytes (only 1 to 3% of the circulating red cells) are found in the circulation.
7. Mature erythrocytes - At this final stage of maturation there is a loss of ribosomes. These cells enter the circulation

Red blood cells do not reproduce, they are manufactured by the body. That is why bone marrow transplants are sometimes required for Leukemia patients.

red cells do not reproduce!!! They are formed in the bone marrow - found in long bones, pelvis and sternum. There are precursor cells here which will differentiate in to various blood elements. The red blood cell gets re cycled!

Red blood cells dont undergo mitosis, they differentiate from germ cells in the bone marrow (stem cells) and then go about their business. Once they reach a certain age they just die, and the bone marrow makes more

they're called cells but they're special type of cells. they're actually produced in bone marrows. did you know that brain cells do not reproduce eventhough they have nuclei?

They are produced in the marrow of the long bones.
