Question

what are the 3 major categories of anemia?

Explanation:

Anemia is a condition where there is a deficiency of red blood cells or hemoglobin. The three major categories are based on the underlying cause. Hemorrhagic anemia occurs due to blood loss. Hemolytic anemia is when red blood cells are destroyed prematurely. Aplastic anemia results from the bone marrow not producing enough red blood cells.

Answer:

The three major categories of anemia are hemorrhagic anemia (due to blood loss), hemolytic anemia (premature red - blood - cell destruction), and aplastic anemia (bone - marrow failure in red - blood - cell production).
