The central organs of hematopoiesis and immune defense in humans include the red bone marrow and thymus. In the red bone marrow, erythrocytes, platelets, granulocytes, and lymphocyte precursors are formed. The thymus is the central organ of lymphopoiesis. Central organs of hematopoiesis - A - red bone marrow (1 - frosty hemocapillary; 2 - reticular tissue; 3 - hematopoietic islets); B - thymus - thymus gland (1 - capsule; 2 - lobules; 3 - layered epithelial bodies in the medulla).   Red Bone Marrow I. HEMOPOETIC CELLS a) The cells of each direction of myelopoiesis are located in the red bone marrow by islets. b) The islets are dominated by cells of the V class of hematopoiesis.   1. Erythropoietic islet a)         a) class IV cells - erythroblasts, b)         cells of class V - ...
