The carbon dioxide in the blood is exchanged for oxygen in the alveoli. These tiny air sacs in the lungs are only one cell thick and they are surrounded by capillaries that are also only one cell thick.Blood from the heart flows through these capillaries and collects oxygen from the alveoli.he alveoli and capillaries both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Attached to the outer walls of alveoli are many tiny blood vessels called capillaries. Essentially, the capillaries are like a netting covering the alveolar sacs. The place where the capillary tissue meets the alveolar tissue creates an extremely thin layer that molecules can pass through.It is called the respiratory membrane. Think of a cartoon where a ghost passes right through the walls.ssentially, the capillaries are like a netting covering the alveolar sacs.
