Question

Quizplus · Accepted Answer

The concept of "interdependence" in the context of alveoli typically refers to the mechanical support that adjacent alveoli provide to each other, not to airflow between them through the pores of Kohn. The pores of Kohn do allow for some air movement between alveoli, but this is not what is typically described as their "interdependence," which more accurately relates to structural support and maintaining open airways.
