The next diagram shows two lung units (S and T) with their blood supplies. Lung unit S has an ideal relationship between blood flow and ventilation. Lung unit T has a comprised blood flow. What is the relationship between alveolar dead space (DALV), physiologic dead space (DPHY) and anatomic dead space (DANAT) for these lung units?
