What do the lungs do?
The lungs are responsible for oxygen exchange and vital to us breathing and living. The 1st blow of air we bring back is from the lubricant material call surfactant which coat the alveolis and allow big surface area for the oxygen to bind and exchange near the CO2. The lung is also responsible to some degree for your level of Bicarbonates. It brings oxygen to the oxygen poor arteries and the heart delivers that to the rest of the body and organs. I hope I answered your query to some degree. I kept it to a minimum. Good Luck.

Distribute oxygen to the rest of the body.
The lungs allow us to lug oxygen from the air, leave behind it into the bloodstream, and remove carbon dioxide and other waste gas to from the bloodstream to be expelled.
You breathe in nouns. Oxygen in the heavens transfers through capillaries within the alveoli and exchanges it for carbon dioxide out of your blood. When you exhale you let out that carbon dioxide and the oxygenated blood travels through your body supplying your tissues and organs next to oxygen. This happens every time you nick a breath in and out.
They exchange unusable gas in your blood for oxygen.

Basically the lungs is where the exchange of gasses occur--CO2 out and O2 contained by. This exchange occurs surrounded by the alveoli. Pulmonary circulation and cardiac circulation is very key and inter-related in providing oxygenization for the integral body--all the cells of the body.
