What is hematopoiesis and where does it primarily take place in the bones?

Hematopoiesis is the breakdown of blood cells, and it primarily takes place in the yellow bone marrow.

Hematopoiesis is the breakdown of blood cells, and it primarily takes place in the compact bone.

Hematopoiesis is the formation of blood cells, and it primarily takes place in the periosteum.

Verified step by step guidance

Understand the term 'hematopoiesis': Hematopoiesis is the process of forming new blood cells, including red blood cells, white blood cells, and platelets.

Identify the primary location of hematopoiesis: In adults, hematopoiesis primarily occurs in the red bone marrow, which is found in certain bones such as the pelvis, vertebrae, sternum, and proximal ends of the femur and humerus.

Differentiate between red and yellow bone marrow: Red bone marrow is involved in blood cell production, while yellow bone marrow primarily stores fat and is not active in hematopoiesis.

Clarify the incorrect options: Hematopoiesis does not occur in the yellow bone marrow or compact bone, and it is not related to the breakdown of blood cells.

Conclude with the correct understanding: Hematopoiesis is the formation of blood cells, and it primarily takes place in the red bone marrow.
