How changes in venous capacitance modulate cardiac output.
Pressure-volume relations, which most directly represent changes in venous capacitance, are useful tools in understanding how changing venous tone modulates cardiac output under both normal physiologic conditions and in disease states. A conceptual model is presented, followed by a discussion of experimental results.
