Not if it's been removed, but lungs can partially repair themselves with deep breathing exercises and a healthy diet and strong immune system. Mine are better now at 78 than they were at 38 when I smoked (quit 40 yrs. ago).
Also, I have lived in areas with relatively clean air since quitting.
don't know, does it grow back.
No. Spleen nodules cannot grow in human or any other lungs. Spleen nodules grow on the spleen. There are nodules that do grow in the lungs, however.
Yes. Think about the size of a babies lungs, and then imagine them inside your chest. It doesn't seem right. Obviously our lungs grow with our bodies.
spotted salamanders grow lungs when they become a juvenile and a adult living on land
snakes and frogs need lungs to help them breath becuse when they grow they don't grow with gills they grom with lungs instead.
A tadpole can breath through their gills but they grow lungs as they turn into a frog.
from the lungs where does it go back
Well, a tadpole, devolopes its lungs when the lungs start to grow.
veins take the CO2 back to the lungs as a waste.
Lung just like any other bird
Many frogs and salamanders start their lives with gills, but when they grow they develop lungs.
The blood carries carbon dioxide back to the lungs and oxygen out of it
