Final answer:
Anemias caused by faulty or decreased RBC production include sickle cell anemia, iron deficiency anemia, vitamin deficiency anemia, and diseases of the bone marrow and stem cells.
Step-by-step explanation:
Anemias caused by faulty or decreased RBC production include sickle cell anemia, iron deficiency anemia, vitamin deficiency anemia, and diseases of the bone marrow and stem cells. Aplastic anemia, for example, is a condition in which there are deficient numbers of RBC stem cells. It can be inherited or triggered by radiation, medication, chemotherapy, or infection. Thalassemia is another inherited condition that affects the maturation of RBCs. Lead exposure can also lead to destruction of the red marrow.
