What is it specifically about substances like mercury and lead that kills you?

I understand something like Carbon Monoxide which physically takes up space that should have oxygen there but what about lead in my blood kills me? Is it a chemical reaction that steals nutrients? Does it puncture blood cells?

That’s not quite accurate. It’s not that Carbon Monoxide takes up space where oxygen should be, but that chemically, your blood has a greater affinity for carbon monoxide than oxygen. That is, given the choice between the two, it actively chooses carbon monoxide over oxygen.
