[Heat transfer by the blood in the venous vessels of the rabbit under different temperature conditions].

The blood temperature in the main venous vessels reflects the formation of the heat balance in the body. In the rabbit posterior vena cava, the temperature increased by 0.19 degrees C-0.26 degrees C after confluence of the kidney and liver veins and decreased by 0.20 degrees C after confluence of the lumbal veins collecting the venous blood from the back muscles and skin vessels. The venous blood temperature in the right auricle was equal to blood temperature in the abdominal artery. When the ambient temperature changed from 22 degrees C-24 degrees C to 35 degrees C-40 degrees C, the temperature in the posterior vena cava and abdominal artery decreased by 0.25 degrees C-0.35 degrees C.
