Theresia Mina answered on 17 Nov 2014:
Indeed a lot of iron molecules form a rock, but in the body it’s really smaller units of iron that is present. We need iron to make heme (that’s what makes red blood cells red) to bind oxygen.

Duane Mellor answered on 17 Nov 2014:
We need a particular type of iron, known as ferrous iron (Fe2+) which can be from haem in meat or as iron salts in other foods. It’s main use is as Theresia says is in haemoglobim in blood, it also works a number of important enzymes in our bodies

Fact: if you lick your fingers, you can sometimes taste something metal, that would be the iron.
