formed by fragmentation of megakaryocytes in the bone marrow (411Allen) 3. Erythropoiesis is the process of red blood cell formation or production which begins in the red bone marrow as a proerythroblast. It then divides several times until it reaches the end of development‚ ejects the nucleus‚ and becomes a reticulocyte. These develop into erythrocytes within one or two days after release from the bone marrow. Erythropoiesis slows down when there is a decrease in oxygen carrying capacity of blood

3. Erythropoiesis is the creation of red blood cells. The making of red blood cells (RBCs) starts in the red blood marrow with another cell called a proerythroblast. The proerythroblast is basically an immature red blood cell. As they mature they then become a reticulocyte. A reticulocyte is the middle‚ or “teenage‚” stage of a RBC. One it fully matures it becomes an erythrocyte. The rate of RBC production is regulated by the percentage of reticulocytes versus RBC circulating. Erythropoiesis is controlled

marrow‚ but some are completed in the lymphatic tissues‚ where they give rise to lymphocytes. (Jenkins‚ Kemnitz‚ & Tortora‚ 2010) 3. Erythropoiesis is the process by which red blood cells are produced. It is stimulated by decreased O2 in circulation‚ which is detected by the kidneys‚ which then secrete the hormone erythroprotein (en.wikipedia.org). Erythropoiesis is speeded up when oxygen delivery to the kidneys falls and slows down when there is sufficient oxygen-carrying capacity of blood. 4

thymus to mature; B-cells also originate in the bone marrow and migrate to the lymph tissues to mature. Erythropoiesis is the production of red blood cells. This process begins with myeloid cells that differentiate into myeloblasts (an immature white blood cell of the bone marrow) or proerythrocytes (an immature red blood cell). There are several factors which influence and regulate erythropoiesis: Erythropoietin- (EPO) a hormone secreted by the kidneys which stimulates the bone marrow to increase

components reutilized the bone marrow is constantly at work produced new erythrocytes. The production of new erythrocytes (erythropoiesis) takes only 4 days. The hemocytoblasts are stem cells in the bone marrow from which all blood cells form. Proerythroblasts are produced by the division and differentiation of stem cells. Basophillic erythroblasts during this stage in erythropoiesis hemoglobin synthesis begins. Intermediate erythroblasts at this time we now see the accumulation of hemoglobin due to its

rupturing. 5. Why do red blood cells live for only about 120 DAYS? This is because they go through a lot of wear and tear as they squeeze through the blood capillaries. 6. What is erythropies? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the production of red blood cells. It is sped up when oxygen delivery to the kidney decreases‚ it slows down when the oxygen carrying capacity of the blood is sufficient. 7. What would happen if a person with type B blood were given
