Question

question:
which of the following are not produced by bone marrow?

answer options:
select one of four
white blood cells
platelets
osteoclasts
red blood cells

Explanation:

• White blood cells, platelets, and red blood cells are all produced by bone marrow (red bone marrow is responsible for hematopoiesis, producing these blood - related cells).
• Osteoclasts are cells that are involved in bone resorption. They are derived from hematopoietic stem cells in the bone marrow but their main function is related to bone tissue, and they are not part of the normal hematopoietic output (the production of blood cells) of the bone marrow in the same way as the other three. So osteoclasts are not produced by bone marrow in the context of blood cell production.

Answer:

Osteoclasts
