anemia. a condition in which there is a reduction in the quantity of either RBC's or hemoglobin in a measured volume of blood, reducing the blood's ability to carry oxygen to the cells: types of anemia include; iron deficiency, folic acid deficiency, pernicious, aplastic, sickle cell, hemorrhagic, and hemolytic.
Low levels of red blood cells, and thus hemoglobin, cause a reduction in the amount of oxygen that can be carried to the body. The decreased delivery of oxygen causes the following symptoms: 1  Fatigue or tiredness. 2  Trouble breathing.3  Rapid heartbeat. 4  Dizziness, light-headedness, inability to concentrate, or headache.nemia occurs because patients canât produce enough red blood cells or because red blood cells are lost through bleeding or destroyed faster than they can be produced. The production of red blood cells in the bone marrow is called erythropoiesis. Erythropoiesis is controlled by red blood cell growth factors.
