In brief: Decreased Hemoglobin

Red blood cells (rbcs) are essentially little bags carrying lots of hemoglobin (hb).
Iron is an important constituent of the hb molecule. Low iron = low hemoglobin = less packing into rbc. Since the RBC is now filled less, a microcytic anemia results.

In brief: Microcytic

Iron is needed in order for the body to produce hemoglobin (hb) -a substance in red blood cells (rbc) that enables them to carry oxygen.
Without hb, RBC will not be able to transport blood to tissues. Microcytosis means the presence of rbcs with a MCV (volume of average rbc) less than normal--smaller rbc. In iron deficiency- there is decreased hb content within the rbc, so it is smaller /microcytic.
