HEMATOLOGY STUDY PACK REVISED EDITION I. Introduction Definition: Hemopoiesis is the process of blood cell formation. Sites of hemopoiesis: Foetus: 0-3 months  yolk sac, 3-5 months  liver and spleen, 5-9 months  Bone marrow. Postnatal life: - Infancy: all bone marrow is haemopoeitic. During childhood, There is progressive fatty replacement of marrow of long bones, so that, by the age of 20 years, the marrow cavities of peripheral bones have stopped producing blood cells “yello...

Pathophysiology Exam 3 Study Guide Hematopoiesis ~9 Questions Distinct features of erythrocytes, what they do, how they do it. • RBCs: responsible for oxygen transport. o Once mature, have no or ganelles, no protein synthesis, do not go through mitosis. Discoid in shape, flexible structure. Life span changes, what happens as they age • Life span of 120 days, +- 20 days o Altered by conditions, decreased in certain conditions. o As RBCs age ▪ Lose flexibility ▪ Lysed or phagocytized ▪ R...
