Explanation:

Anemia occurs when you have a decreased level of hemoglobin in your red blood cells (RBCs). Hemoglobin is the protein in your RBCs that is responsible for carrying oxygen to your tissues. Iron deficiency anemia is the most common type of anemia, and it occurs when your body doesn't have enough of the mineral iron.
