Where is thrombopoietin produced?

  1. Heart

  2. Kidneys

  3. Liver

  4. Spleen

The correct answer is: Liver

Thrombopoietin is produced in the liver. It is a hormone that regulates the production of platelets in the bone marrow. While the heart may produce hormones, thrombopoietin is not one of them. The kidneys may play a role in regulating blood cells and excreting waste, but they do not produce thrombopoietin. The spleen is an organ involved in filtering blood and storing red blood cells, but it does not produce thrombopoietin. Therefore, C Liver is the correct answer.
