Myth 4: The heart is a more important and complex organ than the lungs.
While it’s true that you can’t survive without a heart, you also cannot survive without lungs. Nevertheless, it’s still “easier” to live without much heart function, using mechanical support while awaiting a heart transplant. Lungs have a more complex system that needs to accurately match blood flow with gas flow, while simultaneously needing to be protected from the “outside world.” In contrast, the heart is a relatively simple pump and can be more easily replicated by a mechanical support. Scientists say that artificial, biocompatible hearts may be a reality in the near future, but artificial lungs are “probably 30 years away” due to their complexity.
