Biomicroscopic observations on the regulation of the mesenteric arteriolo-venular anastomoses.
The behaviour of the arteriolo-venular anastomoses was investigated. Observations were completed by the electrical stimulation of the superior mesenteric artery. During stimulation a constriction was induced in the arterioles while the gauge of the anastomoses was almost unchanged. An interpretation of this observation is given.
