It is the heart of course, Our heart is the most powerful muscular organ. Because it pumps blood and can give you an emotional response towards another person. Without it, we would be nothing. Without it, no human would have ever existed at earth. And the heart is the small organ that can give you a long life (BUT IT DEPENDS on how you take care of your body and heart like 80 years or maybe 110 years). .

Heart 
lungs 
brain

If the lungs won't work, the heart's pumping and receiving of blood will be really difficult and will end up to malfunction. If the heart malfunctions because of the lungs... the brain will shut down. 

P.S. Happened to me once, end up to a hospital's CIU
