If we didn't have iron in our body, we will die. Iron is one of the big components of hemoglobin, the essential protein found in erythrocytes. Without iron, hemoglobin would not assemble properly and would not be able to pick up oxygen. Without the blood picking up oxygen, the body will starve and will have an excess build up of CO2. As cells begin to break down due to lack of oxygen, you will die.
