Final answer:
Hematopoiesis is the process by which the formed elements of blood are continuously produced in the red bone marrow. The formed elements include red blood cells, white blood cells, and platelets. Hematopoietic stem cells differentiate into myeloid and lymphoid lineages.
Step-by-step explanation:
Hematopoiesis is the process by which the formed elements of blood are continuously produced in the red bone marrow. The formed elements include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Hematopoietic stem cells differentiate into myeloid and lymphoid lineages, with myeloid stem cells giving rise to most of the formed elements and lymphoid stem cells giving rise to specific types of lymphocytes.
