  6. Learning Objectives. By the end of this section, you will be able to: Compare the composition of atmospheric air and alveolar air. Describe the mechanisms that drive gas exchange. Discuss the importance of sufficient ventilation and perfusion, and how the body adapts when they are insufficient. Discuss the process of external respiration.

  7. Jul 12, 2013 · Oxygen diffuses from the alveoli into the capillaries, which carry it out of the lungs and to the rest of the body; carbon dioxide diffuses into the alveoli and is then exhaled out of the body. The respiratory membrane is the barrier through which oxygen and carbon dioxide are exchanged. Images captured from Visible Body Suite.

  8. Apr 10, 2022 · Gas exchange is the process by which oxygen and carbon dioxide move between the bloodstream and the lungs. This is the primary function of the respiratory system. It is essential to ensure a constant supply of oxygen to tissues, as well as removing carbon dioxide to prevent its accumulation.
