you need it to survive
Because you need them to live.
lungs are tubes that transfer blood from your heart to your lungs and other parts of your body. (doesn't need to be improved)
No you need a heart and a brain too...
There are many vessels serving as conduits between the lungs and the heart. This is because the heart and the lungs need enough oxygenated blood at all times.
Mainly, their heart, liver, kidney, lungs, and bladder.

heart brains lungs
Mainly, their heart, liver, kidney, lungs, and bladder.
The heart is placed very closely to the lungs and it is very practical, because the main blood function which could not be supplemented by any other means is to transfer oxygen and carbon dioxide in and out. Notice how short the veins connecting the heart and the lungs need to be.
