Which organ produces thrombopoietin and clotting factors?

Explanation:
The liver is the main source of both thrombopoietin and most clotting factors. Thrombopoietin acts as the signal that stimulates the bone marrow to produce platelets; the liver provides the primary circulating form of this hormone, helping to regulate platelet production. At the same time, the liver synthesizes most of the proteins needed for coagulation, including the major clotting factors. Other organs may contribute in smaller ways or have different roles (such as storage in the spleen), but they are not the principal producers of thrombopoietin or the majority of clotting factors.
