Answer:
The trachea branches into two bronchi, tubes that lead to the lungs. Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed. ... An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the lungs.
