Red blood cell harmoglobin
Several tissues in the body require iron for proper functioning. These include red blood cells, which use iron to produce hemoglobin for oxygen transportation; muscles, which need iron for optimal oxygen uptake during exercise; and the brain, which relies on iron for normal cognitive function. Additionally, iron is also needed by the liver, spleen, and bone marrow for various metabolic processes.

Iron is what binds to the oxygen in red blood cells (the hemoglobin and myoglobin): low iron (anemia) means that a large portion of red blood cells are unable to bind then carry the oxygen to other tissues in the body - they start to starve for oxygen. Too much Iron also is a problem but it rarely happens unless a person takes too much in a supplement (iron poisoning) or has a birth defect called hemochromatosis (dystopic blood-color: too much red )

Minerals are part of all the tissues in the body, eg: Calcium, Iron, Mg, Mn, Selenium, etc.
The iron-containing pigment of the erythrocytes that transports oxygen from the lungs to all of the body tissues would be "Hemoglobin".
hemoglobin
you need iron for your blood and your thyroid.
In the human body, iron is present in all cells and has several vital functions -as a carrier of oxygen to the tissues from the lungs in the form of hemoglobin, -as a transport medium for electrons within the cells in the form of cytochromes -as an integral part of enzyme reactions in various tissues. Too little iron can interfere with these vital functions and lead to morbidity and death.
Ferritin is a protein that stores iron and releases it in a controlled fashion. Hence, the body has a "buffer" against iron deficiency (if the blood has too little iron, ferritin can release more) and, to a lesser extent, iron overload (if the blood and tissues of the body have too much iron, ferritin can help to store the excess iron).
so tissues in your body can grow and repair themselves
yes, because you need iron in your body but too much is also not good
Hemoglobin is a protein in Red Blood Cells, it delivers OXYGEN to tissues and Iron is required for this.
Iron is a mineral and functions primarily as a carrier of oxygen in the body.
The body has a limited capacity for iron, which means it can easily build up in organs like your liver, heart and pancreas. This is dangerous because iron is a potent oxidizer and can damage your body tissues contributing to serious health issues.
as this gives oxygen to your lungs as you need air to breathe!
Yes, the circulatory system is responsible for transporting hormones to body tissues. It also carries oxygen, nutrients, and waste to where they need to be.
