Capillary volume and length in control and hypoxic animals

	Control (n = 7)	Hypoxic (n = 6)
Capillary volume density (cm3 cm−3)	0.09 ± 0.005	0.13 ± 0.01*
Total capillary volume (cm3 LL−1)	0.19 ± 0.019	0.43 ± 0.03*
Capillary length density (× 105 cm cm−3)	4.02 ± 0.19	5.24 ± 0.29*
Total capillary length (× 105 cm LL−1)	8.07 ± 0.60	17.56 ± 0.56*

Values are means (± S.E.M.). Capillary volume density, capillary volume per unit volume of lung. Total capillary volume, capillary volume per left lung. Capillary length density, capillary length per unit volume of lung. Total capillary length, capillary length per left lung.

^*Significant difference from controls (P < 0.01, t test).
