IRON
The metal element that carries oxygen in the blood is iron, which is incorporated in the hemoglobin molecule.
Lead is a metal that can have harmful effects on blood cells. Exposure to lead can lead to decreased production of red blood cells, known as anemia, as well as interfere with the function of white blood cells. Lead poisoning can cause damage to the bone marrow, where blood cells are produced, resulting in various blood cell abnormalities.
Iron plays a key role in blood clot formation by aiding in the production of hemoglobin, a protein that helps red blood cells carry oxygen. Additionally, calcium is another mineral that plays a critical role in the coagulation process by helping activate clotting factors.
You can use steel and flint to make a fire and cook food. Steel is a metal alloy.Copper can be used to make a statue of a woman with a torch, tablet, and crown.Iron is used by the hemoglobin in blood to carry oxygen to the body.
Iron is the metal element that carries oxygen in the blood. It is a key component of hemoglobin, the protein in red blood cells that binds to oxygen and transports it throughout the body.
copper
Blood contains iron, which is essential for carrying oxygen in red blood cells. When blood is exposed to air, the iron in hemoglobin reacts with oxygen and creates a metallic scent. This reaction is what gives blood its characteristic metallic smell.
In the blood of vertebrates and some invertebrates iron ions bound in a protein complex called hemoglobin transports oxygen. In the blood of many invertebrates copper ions bound in a protein complex called hemocyanin transports oxygen. However it is very likely that unbound sodium ions in the blood plasma outnumber the iron ions or copper ions in either case.
The metal that is most important for blood is iron. Iron is a crucial component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body.
All oxygen transportation chemicals in animals employ a metal ion in the centre of a globin group. In higher animals it is Iron (the heme of hemaglobin), in the horseshoe crab it is Copper, which is why they have blue blood. In certain hemi-cordates it is zinc which gives them purple blood.
Oxygen is a non-metal
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.
