The Lungs

One of the major functions of the lungs is to

bring oxygen to the blood vessels so it can be

transported throughout the body. As you will

recall, oxygen is necessary to make ATP. Your

lungs are specifically designed to efficiently

transport oxygen. Small tubes known as

bronchi and bronchioles transport oxygen to all

areas of the lungs. This oxygen will then reach

structures known as alveoli which is where the

oxygen will cross into the bloodstream.
