The blood microcirculatory bed of the small intestine, liver and pancreas after resection of the stomach and small intestine

As demonstrate the experiments performed on dogs and rats, after surgical intervention to the stomach and small intestine, other organs of the digestive system experience an increased functional loading, that results in noticeable changes in the intraorganic blood vessels and the blood microcirculatory bed organs. The course of the compensatory processes occurs with a definite regularity--as stages. The first stage is characterized with a predominance of the pathological reactions over the compensatory ones, in the second stage certain compensatory possibilities of the organism are noted. In the third stage the compensatory-adaptive reactions prevail over the pathological processes in the blood vessels and blood microcirculatory bed.
