Population
29 cat mesenteric arterioles with an average diameter of 25.1 micrometers
Comparison
Arterial pressure reduction (range 120-40 mmHg) vs Baseline/higher arterial pressure

Supports dual autoregulatory mechanisms in arterioles; leaves open translation to human physiology and practice.
Does arterial pressure reduction affect vessel diameter, wall tension, and flow in cat mesenteric arterioles?
The study supports the hypotheses that both wall tension and flow regulation are important mechanisms in the autoregulatory response of mesenteric arterioles to changes in arterial pressure.
Burrows et al. (1981) studied this question.
