Experiments were conducted on dogs. With the fall of body temperature from 36 to 24 degrees C the circulation volume of the spleen decreased from 53.9 +/- 1.94 to 17.9 +/- 0.84 ml/100 g/min, and the arterio-venous difference by oxyhemoglobin - from 19.5 +/- 0.58 to 3.3 +/- 0.23%. Marked body overcooling completely depressed the capacity of the spleen to extract low-resistant erythrocytes from the circulation. A fall of body temperature from 36 to 30 degrees C was accompanied by reduction of the splenic area to 92.6 +/- 2.6%; subsequent chilling led to the accumulation of blood in the pulp with increase of the organ area to 108.7 +/- 4.82%.
