Q

ventilation occurs to a greater degree from _ to base
gravity stretches lungs __, thus at end expiration, alveoli at apex are more expanded
a smaller amount of air is then __

zone 1 perfusion occurs at __ w hemorrhage or high alveolar pressures

zone 3 found in __ regions
arterial > __> alveolar
blood flow is __ as alveolar pressure is lowest
when supine, diff in perfusion is __ as gravity affects all lung the same
