Human biologyBlood
Quick Answer
Hemoglobin in red blood cells contains most of the body’s iron. Iron is essential because it lets hemoglobin bind and transport oxygen.
The Full Story
Hemoglobin, the oxygen-carrying protein in red blood cells, contains the majority of iron in the human body. Iron atoms in hemoglobin bind oxygen in the lungs and release it in tissues that need energy. The body recycles iron efficiently from old red blood cells, since it is too valuable to waste. Iron deficiency is common worldwide and can lead to anemia, fatigue, and reduced exercise capacity.
