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.
Best Answer: The lungs themselves are incredibly elastic air balloons. Their elasticity believe it or not is mostly due to a protein called surfactant, which greatly reduces surface tension, allowing the lung to expand greatly.he diaphragm's contraction in essence expands the chest wall (aka thoracic cavity), which in turn increases the intra-thoracic pressure. This increased pressure pulls on the lungs, and this is what actually draws air into them.
