Why does our blood don’t get rusted even if it contains iron and oxygen?

Hint: Rust may be a sort of iron oxide. It occurs when iron combines with the oxygen within the air causing it to corrode. Rust can affect iron and its alloys, including steel. The most catalyst for rust to occur is water. Although iron and steel structures seem solid to the attention , water molecules are ready to penetrate microscopic gaps within the metal. This starts the method of corrosion. If salt is present.

Complete answer:
Blood may be a liquid body substance in humans and other animals that delivers necessary substances like nutrients and oxygen to the cells and transports metabolic waste products faraway from those self same cells. In vertebrates it's composed of blood cells suspended in plasma .

Our blood doesn’t get rusted albeit it contains iron and oxygen because rust is made when oxide combines with water molecules to make the oxidized iron Fe and hydrated water molecules. The iron contents in our body are within the Fe oxidized sort of iron and it doesn't combine with water molecules.

The iron present in our body cannot absorb ferric iron, only ferrous iron is absorbed. Hence the physical body doesn't get rusted even within the presence of iron and oxygen in our body.Oxygen sticks to the iron here and moves round the body. So we will say iron is important in our lives not simply because of the advantages it provides, but because it carries oxygen around our body, thus making us stay alive.

Note: We cannot live without oxygen, and it's the red blood cells that deliver this oxygen to cells everywhere in the body. A molecule called hemoglobin within the red blood cells contains iron.
