Key result
The pressure-flow relationship in isolated denervated intestinal loops of the dog was curvilinear and convex to the pressure axis, with flow starting at a minimal pressure of 16 mm Hg.
In isolated dog intestinal loops, the pressure-flow relationship is curvilinear and influenced by critical closure, passive expansion, and anomalous blood viscosity.

Caution against clinical translation in intestinal perfusion; leaves open critical closure mechanisms in vivo.
Selkurt et al. (1958) studied this question. Pressure variation was evaluated on Pressure-flow relationship. The pressure-flow relationship in isolated denervated intestinal loops of the dog was curvilinear and convex to the pressure axis, with flow starting at a minimal pressure of 16 mm Hg.
