GENERAL HISTOLOGY

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: -Where does hematopoiesis occur? The most common site of blood cell production is the spongy tissue inside of your bones called bone marrow. Hematopoiesis that occurs in your bone marrow is called medullary hematopoiesis. Blood cells get made in your bone marrow and released into your bloodstream.

Detailed explanation-3: -In children, haematopoiesis occurs in the marrow of the long bones such as the femur and tibia. In adults, it occurs mainly in the pelvis, cranium, vertebrae, and sternum.

Detailed explanation-4: -Hematopoiesis is the process of creating a wide variety of blood and bone marrow cells, namely erythrocytes, platelets, granulocytes, lymphocytes, and monocytes.
