WebOct 29, 2024 · The lungs also help remove gaseous waste products from the body. The process of bringing air into the body, extracting oxygen, delivering it to the tissues of the body, and removing carbon dioxide—a potentially harmful gas that’s eliminated during respiration—is complex. WebThe volume of air that does participate in gas exchange, because it is in contact with perfused alveoli, is termed the alveolar ventilation (V. a = V. e − V. d). The volume per minute of alveolar ventilation is critical, because it determines the amount of air presented to alveoli into which carbon dioxide can be excreted and from which ...
