Abstract
Experiments conducted on 10 male Wistar rats established various adaptive reactions of the rate of blood flow in the stomach and jejunum of hungry and well-fed animals to a stress state modelled by hypothermia. During the period of maximum body cooling (below 32°C), in hungry and well-fed animals, the rate of blood flow in the stomach showed no significant changes. In the jejunum, the rate of blood flow in hungry animals tended to slow down, while it increased significantly in well-fed animals.
