Randomized trial examines oxygen consumption in arterioles and venules, indicating species differences and hypoxia resistance.

This study aims to measure and compare the oxygen consumption rates in mesenteric arterioles and venules from different species.
Measured oxygen consumption using the Cartesian diver microrespirometer in hamster and human vessels.
Compared oxygen consumption rates across different vessel diameters in vitro.
Evaluated vessel responses to varying environmental oxygen tensions.
Oxygen consumption averaged 1.05 µliter/mg/hr for arterioles <150 µ in diameter and 0.58 µliter/mg/hr for arteries 250 to 400 µ.
Hamster venules had an average oxygen consumption of 0.53 µliter/mg/hr, similar to larger arteries.
Human mesenteric arteries and veins showed lower consumption rates of 0.35 and 0.25 µliter/mg/hr, respectively.

Howard et al. (1965) studied this question.
