The iron in the blood is not metallic iron. Metallic iron reacts with oxygen to form rust:
4 Fe (s) + 3 O2 (g) --> 2 Fe2O3 (s)
Most of the iron in the blood is already combined (such as in hemoglobin) or is in the form of complex ions.

The main purpose of blood is to carry oxygen and the effective oxygen-carrier is the iron present in the haemoglobin. In fact in layman words we can say the iron gets rusted in our blood which scientifically mean what we say the Iron is oxidized.By this way the oxygen is carried all over in our body effectively.
This property of rusting gives red color to the oxygenated blood. This is the reason why the impure blood( without oxygen) is not that red(you can see bluish color of the veins on your hand which carry impure blood).
The only difference with this type of rusting and the rusting we see of iron things is- In our body the oxygen bonded with Iron is only for a very short period and is grabbed by the mitochondria of our cells whereas in the typical rusting we see, it is a permanent bonding between Iron and oxygen.
It's an interesting question to answer. Thankyou

Iron rusts only in continuous presence of water and oxygen . Moreover Iron present is in compounds and there is no free iron.

Blood does not contain iron, but the pigment(haemoglobin) contains the iron. And haemoglobin helps in the transfer of respiratory gases.
For any reaction, a suitable environment must be created and inside the body it doesn't have one
While evolving, our body has shown it's intelligence. If there was rusting of iron inside our body, can you imagine how funny or dangerous it would be?

The iron is somewhat protected by a heme molecule (hemoglobin). The structure of the hemoglobin allows the oxygen to approach the iron, but it doesn't allow a really strong bond to be formed. That is why the oxygen is then able to get away from the hemoglobin when it is time for it to be released in the tissues where it is needed.

The rusting of iron takes place in the presence of air and moisture.In the body,iron,oxygen and moisture are not in contact so therefore it does not rust.

because iron fo rusting needs both presence of oxygen and water theris no hydrogen in blood will makes itater it is afluid not awater so iron cant get rusted

as oxygen contained inthe blood is in the form of a complex compound named as oxyhaemoglobin which donot react with iron hence dont get corroded.

because iron is bounded with eqvelent bond and hence is not free...so i can not bind with oxygen to make rust

That is because Iron is not in too large numbers .
