[The system of blood vessels in the glandular and muscular stomach of the chicken (author's transl)].
The vascular system of the stomach of the chicken was investigated by means of corrosion preparations as well as by light- and electronmicroscopic methods. The main vessels form a) an Intermuscular Plexus the outer longitudinal and inner circular layers of the muscle wall in the glandular stomach and b) a Subserous Plexus in the muscular stomach. In the glandular stomach the Interglandular Parietal Arterial Plexus I, situated below the Lamina muscularis mucosae I arises from the arteries which pass through gaps in the muscle wall. This Plexus I produces another plexus, the Interglandular Arterial Plexus II, located on top of the Lamina muscularis mucosae I. Both arterial plexuses are accompanied by venous plexuses, which convey the blood into a Subglandular Venous Plexus. -The vessels of the muscular stomach provide the predominant supply of blood to the muscle wall. The mucous membrane of the muscular stomach is vascularized far less than the one in the glandular stomach. -The hemodynamic relationships of the vessels of the hen's stomach and the significance of the fine structure of the subepithelial capillaries and venules for the exchange of materials are discussed.
