AThe spleen and thymus
BThe bone marrow alone
CThe liver and kidneys
DThe lungs and spleen
Answer & Solution
Correct answer: C. The liver and kidneys
1. Thrombopoietin is a glycoprotein hormone like erythropoietin.
2. It is produced by the liver and the kidneys.
3. Its action is to drive megakaryocytes on to shed platelets.
4. The bone marrow is where its target cells live, not where the hormone is made, which makes that option the natural trap.
