Experiments were performed to determine the extent to which thoracic translocation of blood and abdominal compression contribute to the diuresis and natriuresis during head-out water immersion in the anesthetized nonhuman primate. Neither a diuresis nor natriuresis occurred in animals immersed in the recumbent posture to a depth such that the abdomen was subjected to the same water pressure as during head-out upright immersion. It is concluded that the abdominal compression observed during upright immersion does not contribute per se to the renal responses and that the immersion-induced translocation of blood to the thorax may be the causal factor during this volume stimulus.
