Alveoli
Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

The path of air resembles the path of blood in the circulatory system. It starts off with bigger tubes, and as it moves in deeper into the lungs, it goes through intensive and extensive branching to reach the site of gas exchange (alveoli). Study the anatomy of the lungs and follow the path of air through the respiratory structures.
