Question

Quizplus · Accepted Answer

Alveolar deadspace refers to the portion of alveolar ventilation that does not participate in gas exchange because it lacks perfusion by pulmonary capillaries. Anatomic deadspace (B) refers to the airways that do not participate in gas exchange, such as the trachea, bronchi, and bronchioles. Physiologic deadspace (C) is the sum of alveolar deadspace and anatomic deadspace, and reflects the total volume of inspired air that does not participate in gas exchange. Minute alveolar ventilation (D) refers to the total amount of air that enters the alveoli per minute, regardless of whether or not it participates in gas exchange.
