Conclusion Questions 3.3.1 1. The walls of the alveoli in the lungs are incredibly thin. Explain how this structure is related to function in the body. The walls of the alveoli are extremely thin so that they can serve their purpose of allowing diffusion of oxygen and carbon dioxide to happen. This is where gas exchange occurs.
They act to increase the surface area of each lung and therefore increase the amount of blood that can absorb oxygen in one breath. Together, the millions of alveoli of the lungs form a surface of more than 100 square meters. Within the alveolar walls is a dense network of tiny blood vessels called capillaries.
