Capillaries
Between the avioli and the lungs.
Gas exchange does not occur in the pleura. The pleura is a membrane that lines the outside of the lungs and inside of the chest cavity. Gas exchange, where oxygen is taken in and carbon dioxide is removed, happens in the alveoli of the lungs.
Gas exchange occurs in the alveoli of the lungs. These tiny air sacs are surrounded by capillaries where oxygen from the air can enter the bloodstream and carbon dioxide can be removed from the blood.
blood takes oxygen and gives carbon dioxide to the lungs
The gas that we don't use in our lungs we breathe out again.
oxigen is the gas that enters the blood through the lungs
The blood picks up oxygen in the lungs. It dumps carbon dioxide, too. That's the standard gas exchange. There is a bit more to this, but this is the essential life-continuing transaction that must occur.
The chlorine in mustard gas bonds with the water in your lungs to form hydrochloric acid and burns your lungs
