general air flow
-
-
as airway length decreases, air flow increases
-
-
calibre
as calibre of airways decreases, the flow of air decreases by a more significant amount
-
resistance
combined sectional airw of daughter branches exceeds the cross sectional area of the parent branch so resistance remains constant
-
-
-
bronchiole smooth muscle
spiral muscle alters length and diameter of airways which allows for the balance of anatomical dead space against resistance to airflow
