In the measurement of the length of preserved intestine after massive resection of the length of intestine as it is at the time of operation may produce an error when compared to the length of the intestine at normal times. Therefore, attention was paid to the number of arteriae rectae of the intestinal artery and a comparison was made between such number and the length of the intestine at normal condition in rats and man. The length of the small intestine of the rats (177 rats) showed uniform in the rats of same age group. The number of arteriae rectae of rats fell within a narrow range of 280-326 and its mean value was 299. In human beings, the length of the intestine was observed to increase as the body length increases. The average number of the arteriae rectae was 433. As a result, the conclusion was drawn that the measurement of arteriae rectae of the intestinal artery is useful for the estimation of preserved intestine at normal condition.
