title: [The participation of cardiac, vascular and coronary components in the shaping of cardiovascular reactions to head-down tilt exposures].
abstract: An increase in venous flow to the heart due to the 15-45 degrees head-down inclination of the cat, induced a drop in arterial pressure combined mostly with an increased cardiac output and changes of coronary blood flow. The character and obviousness of the responses did not depend on the inclination angle. Initial level of arterial pressure was found to be significant for subsequent responses to the antiorthostatism: the pressure increased at a low initial level and decreased at a high one.
