Abstract

It is well known that the organism is capable of maintaining his homeostasis when he is exposed to various kinds of stress. This paper reports an investigation of the functions of the liver in low temperature environment from the view-point of the hemodynamic changes in order to clarify the homeostatic control of bodies. The findings were summarized as follows; The exposure to cold induced a congestion in the liver and an oligemia in the area of the head and extremitas. The circulation blood was concentrated to the liver in about 3 minutes after the body had been exposed to cold. The congestion in the liver also occurred by intermittently soaking the extremitas to cold water, by intravenous injection of adrenalin, or by other kinds of stress. It is suggested that the liver has the functions of storing the blood and of releasing it into the circulatory system in emergency state.
