[Resistive, capacitive and metabolic functions of the vessels of the small intestine in acute hypoxic hypoxia].

In acute experiments on cats, under conditions of autoperfusion of the small intestine vessels, acute hypoxic hypoxia led to a ahort-term increase of the precapillary resistance and a stable decrease of the postcapillary one, to a decrease of capillary hydrostatic pressure and absorption of fluid from the interstitial space into the blood with an increase of the axchange surface. The mechanisms of above vascular and filtration-absorbent changes in the intestine during hypoxia, are discussed.
