Detailed explanation-1: -In humans, hematopoiesis begins in the yolk sac and transitions into the liver temporarily before finally establishing definitive hematopoiesis in the bone marrow and thymus.
Detailed explanation-2: -After birth, and during early childhood, hematopoiesis occurs in the red marrow of the bone. With age, hematopoiesis becomes restricted to the skull, sternum, ribs, vertebrae, and pelvis. Yellow marrow, comprised of fat cells, replaces the red marrow and limits its potential for hematopoiesis.
Detailed explanation-3: -In adults, hematopoiesis of red blood cells and platelets occurs primarily in the bone marrow. In infants and children, it may also continue in the spleen and liver. The lymph system, particularly the spleen, lymph nodes, and thymus, produces a type of white blood cell called lymphocytes.
