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 site of hematopoiesis in adults: In adults, hematopoiesis primarily occurs in the red bone marrow.

Recognize the role of red bone marrow: Red bone marrow is found in the cavities of certain bones, such as the pelvis, vertebrae, sternum, and proximal ends of the femur and humerus.

Differentiate other organs involved in blood cell formation: While the thymus, spleen, and liver have roles in the immune system and blood cell regulation, they are not the primary sites of hematopoiesis in adults.

Conclude with the correct answer: The primary site of hematopoiesis in adults is the red bone marrow, not the thymus, spleen, or liver.
