Your logic is all gassy. Must be eating too many pakoraas.

Do you need barriers for your blood to get oxygen from your lungs? The same way blood flows through two lungs, it could flow through two hearts

The problem is that heart is not a purification device. It is the pumping device. The blood doesn’t simply flows through, it is pumped and I think it would be much complicated to regulate 2 hearts instead of 1 [possible, better but complicated]. I think 2 circuits would make things simpler. Ask Doctor Who.

One theory is that vital organs like heart, brain, stomach, etc. were developed earlier in evolutionary stages and other organs were developed later and therefore later technology allowed us to have redundant parts.
