Moderator note:
Good clear explanation.
The red blood cells are stimulated to mature by a hormone called Erythropoietin , which is synthesized from the kidneys. Therefore, people with chronic kidney failure are usually anemic as less red blood cells are made.
Although the heart and the lungs are main organs in the blood circulation, diseases involving these organs don't necessarily lead to anemia but usually manifest themselves as shortness of breath.
Liver diseases can cause many metabolic problems but usually result in jaundice rather than anemia.
Finally, even though the spleen is rich with blood and vessels, it only regulates the turn-over rate of old blood cells. In fact, patients whose spleens are removed can live normally without any anemia.
