Question

Define the process of formation of blood cells.

Answer 1

Hemopoiesis ( hematopoiesis) is the process that produces the formed elements of the blood. Hemopoiesis takes place in the red bone marrow found in the epiphyses of long bones (for example, the humerus and femur), flat bones (ribs and cranial bones), vertebrae, and the pelvis.

Blood cells are made in the bone marrow . That's a spongy tissue located inside some bones. These blood-forming stem cells can grow into all 3 types of blood cells – red cells, white cells and platelets.

Answer 2

Hematopoiesis, or Hemopoiesis, continuous process by which the cellular constituents of blood are replenished as needed. Blood cells are divided into three groups: the red blood cells (erythrocytes), the white blood cells (leukocytes), and the blood platelets (thrombocytes). The white blood cells are subdivided into three broad groups: granulocytes, lymphocytes, and monocytes
