Yes it is absolutely true that each lung is fed oxygen by a separate bronchus. There are actually two lungs and two bronchi. Each of the two lungs are safeguarded by the two ribcages as
they are placed within the rib cages. The lungs actually consists of elastic
sacs that contract and expand for taking in and releasing air. This way oxygen
is passed into the blood and carbon dioxide is taken out from the blood and
passed out. This is also the main function of the lungs.
