pulmonary venules [ effective lumen radius ( elr ) , 116 +/- 2 microns ] with an adherent layer of parenchyma responded to hypoxia and anoxia with a graded sustained contraction ( hypoxia , 0.03 +/- 0.01 ; anoxia , 0.26 +/- 0.03 mn/mm ) , whereas paired femoral venules ( elr , 184 +/- 7 microns ) contracted to anoxia only ( 0.05 +/- 0.02 mn/mm ) .
