Explain how are the lungs adapted for fast gas exchange?

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. WebThe human respiratory system is adapted to allow air to pass in and out of the body, and for efficient gas exchange to happen.
