CHICAGO, March 13 (UPI) -- Pope Francis had one lung removed because of an infection when he was a teen, but it should not slow him down as pontiff, a U.S. expert says.

Dr. Daniel Dilling, a pulmonologist at the Loyola University Medical Center near Chicago, said lungs are to a certain extent "overbuilt" and have a good deal of reserve volume.

"A person with two lungs has a lot of reserve function, so if one lung is removed, he or she can still function normally, without shortness of breath," Dilling said in a statement. "You can live no problem with one lung."

However, if a person with one lung suffers a lung disease, he or she will not have any reserve capacity to compensate for loss of lung function, Dilling said.
