Vascular pattern in the pancreas of the cat

Summary The pathways of microcirculation in the pancreas of the cat were investigated by scanning electron microscopy of Mercox preparations of the vascular bed. A portal system from islet to exocrine vessels as well as a direct arterial flow to the exocrine pancreas have been observed. Sphincters appear to exist in portal capillaries at the border between the endocrine and exocrine portions of the pancreas. Islets possess an independent venous drainage.A portion of these results was presented on the occasion of the 6th European Anatomical Congress, Hamburg 1981 (see Syed Ali 1981, for abstract).
