Liver synthesizes all, except
Liver synthesizes clotting factors such as fibrinogen(I), factors V, VII, IX & X. Liver synthesizes Haptoglobin which binds free hemoglobin released from erythrocytes with high affinity and thereby inhibits its oxidative activity. Liver synthesizes C3 complement which is chemotactic & plays a role in opsonization. Immunoglobulins are secreted from plasma cells & play a role in defense mechanism of body.Ref: Medical Physiology, Indu Khurana
