Abstract
Generalized alterations in venous tone may shift large amounts of blood within the vascular system. Both physical and emotional stimuli are capable of affecting venous tone. The present report is a study in healthy males of the effects of certain of these factors on pressure (tone) in a peripheral vein segment isolated by means of specially designed, Plexiglas vein occluders. The emotional stimuli employed were the most effective of the group in increasing venous tone.
