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.
Gaseous exchange between the blood and air takes place in the alveoli, but the detailed structure of the alveolar walls cannot be resolved with the light microscope. This shows a photograph of a section of adult lung.he air spaces are within 0.2Âµm of the blood, which is a very thin barrier to diffusion. This arrangement means there is a fast efficient transfer of oxygen and carbon dioxide between the blood and the air, the major function of the respiratory portion.
