ANATOMY

Detailed explanation-1: -About 70 percent of your body’s iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.

Detailed explanation-2: -Hemoglobin is the most important component of red blood cells. It is composed of a protein called heme, which binds oxygen.

Detailed explanation-3: -In these heme proteins, the iron(II)–dioxygen bond does a vital function in their physiology. It is in the ferrous form that myoglobin or hemoglobin can bind molecular oxygen reversibly and carry out its physiological function.

Detailed explanation-4: -Iron is a major component of hemoglobin, a type of protein in red blood cells that carries oxygen from your lungs to all parts of the body. Without enough iron, there aren’t enough red blood cells to transport oxygen, which leads to fatigue.

Detailed explanation-5: -Hemoglobin contains iron, which allows it to pick up oxygen from the air we breathe and deliver it everywhere in the body. You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells.
