WebThe Respiratory System: The lungs are major organs of the respiratory system. Structures within the lungs play an important role in the process of gas exchange. Gas exchange allows oxygen to move from the respiratory system into the bloodstream and moves carbon dioxide from the blood into the lungs. Web22 de fev. de 2024 · Adaptations of the alveoli: Moist walls – gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls – allow gases to pass through. Extensive blood supply – ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.
