The contributions of active and passive wall tension to regulation of arteriolar diameters were determined for large (1A), intermediate (2A), and small (3A) arterioles in the small intestine of the anesthetized rat. Active tension (Ta) contributed greater than 85% of total wall force at rest in 2A and 3A and 75-80% of total force in 1A. Ta was approximately 90% of peak active tension (Ta,peak) for large through small arterioles, even though absolute Ta varied by fourfold. A linear relationship… CONTINUE READING
