[Relations between disorders of the intestinal-hepatic basin hemodynamics and absorption function in hemorrhage]

Chronic dog experiments showed that blood loss of 30 ml/kg or an intravenous injection of 1 microgram/kg norepinephrine did not markedly change small intestinal absorption. Blood supply to the liver was maintained at the expense of restricted portal circulation. Adaptation in blood loss seems to support arterial blood supply to the liver and absorbing epithelium of the small intestine to warrant their resistance to circulatory hypoxia and to promote their functional activity.
