red blood cells are mainly hemoglobin. hemoglobin is mostly iron. hemoglobin binds oxygen and transports it to the body. when it is low, heart rate goes up and the heart works much harder to get oxygen to the body. thus, one feels tired so that the body will slow down and the heart can pump the blood to the tissues.
