Question

Quizplus · Accepted Answer

Erythrocytes (RBCs)are flexible biconcave disks without nuclei whose primary component is an oxygen-carrying molecule called hemoglobin.RBCs are generated from precursor stem cells under the influence of a growth factor called erythropoietin.Erythropoietin is secreted by the kidney in response to a perceived decrease in perfusion or tissue hypoxia.Reticulocytes are immature RBCs that may be released when there is a demand for RBCs that exceeds the number of available mature cells.The oxygen affinity for hemoglobin is modulated primarily by the concentration of 2,3-diphosphoglycerate (2,3-DPG)and depends on the blood pH and body temperature.
