A correlation of responses of the resistance and capacitance vessels of the intestine and kidney to changes of impulse in postganglionic nerves under pressor reflexes

Abstract

The responses of resistance vessels of the intestine and kidney were induced by high amplitude impulses (over 15 muV), while those of capacitance vessels in these organs were induced by low amplitude impulses (15 muV and lower) of postganglionic sympathetic fibres.

Vascular capacitance: Its control and importance

“…It is possible that responses might have been greater if carotid pressure had changed over a wider range. Responses of intestinal capacitance vesvels to carotid occlusion have also been reported by Hadjiminas and Oberg (1968), Samoilenko and Tkachenko (1971) and Tkachenko et al (1978). However, Hadjiminas and Oberg (1968) did not control intestinal blood flow and the other two papers do not give any quantitative data.…”
