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.
The alveoli are adapted for gas exchange with a large surface area, with each alveolus having a 1-cell thick wall, and numerous capillaries covering it [18]. These capillaries are also 1-cell thick [19], leaving a barrier of less than 1Î¼m between the oxygenated air and bloodstream [20].
