It carries oxygen from the lungs to the body tissues and take carbon dioxide from the tissues to the lungs.

About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin.iron is a component of certain proteins, essential for respiration and energy metabolism so it is also a source of iron compound.

hemoglobin interacts with nitric oxide (NO) to regulate the blood pressure. NO is made by the endothelial cells and by virtue of its action on the vascular smooth muscle leads to vasodilation.

outside the brain, hemoglobin has an non-oxygen carrying functions as an antioxidant and a regulator of iron metabolism in macrophages, alveolar cells, and in mesangial ceels in the kidney.

Hemoglobin is an iron-protein compound in red blood cells that gives blood its red color.
Hb is a conjugated protein present in RBCs. It carries oxygen from the lungs to the tissue cells, and carbondioxide- the gaseous waste -from the cells to the lungs.

Hemoglobin, the protein in red blood cells, carries oxygen from the lungs to all parts of the body, and collects carbon dioxide, returning it to the lungs to be expelled.
