Iron and hemoglobin ( a substance found in your red blood cells) combine with oxygen and it turns the blood color from a dark color, to a healthy bright color, also iron picks up oxygen, and carries it through the rest of your body.
the reaction between iron metal and oxygen gas making solid iron oxide
Iron is part of the haemoglobin molecule. Oxygen binds with iron to be transported around the body.
Iron is a mineral and functions primarily as a carrier of oxygen in the body.
Oxygen
rust is caused by the interaction of the iron and the oxygen in the air. when iron is painted, there is a barrier between the iron and oxygen.
I'm pretty sure its something like calcium or iron... but you better check, just in case It is iron, because when exposed to oxygen, it turns red because together they form rust. This is also why blood has a metalic taste.
Iron is an important part of hemoglobin, the protein that helps your blood carry oxygen.
Iron is a main part of hemoglobin, which is a protein in your red blood cells. Red blood cells carry oxygen to the body, and oxygen binds to the iron that is in the hemoglobin. Therefore having low iron can make it harder for your body to make red blood cells and less oxygen will be carried to your body, causing fatigue and other problems.

Iron is an important component for the parts of our blood that transports oxygen.
