| Abstract: | Relative changes in local blood volume in 46 vascular regions of the body after moderate and severe blood loss are described. Moderate blood loss caused a redistribution of blood from the skin of the chest and hind limbs, most organs of the abdomen and pelvis, the muscular and bony tissues of the abdomen, pelvis, and limbs to the brain, heart, lungs, kidneys, stomach and to the muscles of the head and neck. After severe blood loss the changes were similar but the blood volume in the kidneys and stomach was reduced; a relative increase in the blood volume in the muscular and bony tissues of the thorax also was observed. The intensity of the redistributive response to severe blood loss was less than to a moderate blood loss.Central Research Laboratory, S. M. Kirov Leningrad Postgraduate Medical Institute.
