Analysis of Cardiac Output and Venous Return Curves:
The cardiac output curve and venous return curve depict the changes in them with changing right atrial pressure. Venous return and cardiac output can be equal at only one point where both curves intersect each other. Sympathetic stimulation, positive inotropic agents, etc shift the cardiac output curve upwards. Inhibition of sympathetic activity, negative ionotropic agents, and certain disease conditions move this curve downwards. An increase in intrapleural pressure shifts the curve to the right, and a decrease shifts it to the left. An increase in blood volume and increased venous tone shifts the venous return curve upwards. And decrease in blood volume and venous tone moves the curve downwards. An increase in arteriolar tone decreases the slope of the curve. And decrease in the arteriolar tone increases the slope.

The best explanation ever. No channel explained this complex concept as clear as this channel. Thank you 🙏🙏🙏

Thank you very much

THANKS SO MUCH FOR THIS VID!!!
I have a question though:
If an increase in sympathetic tone leads to both venoconstriction (thus increasing MSFP and shifting the venous return curve to the right) and arterial vasoconstriction (thus potentially shifting the venous return curve to the left), then why is it indicated in the concluding image regarding the possible factors that can lead to a new equilibrium point (in the examples: blood transfusion, positive inotropic agent, and increased sympathetic tone) that, in the case of increased sympathetic tone, there is an overall rightward shift of the venous return curve? Doesn't increased sympathetic tone necessarily include arterial vasoconstriction alongside venoconstriction?

great job, watched this right before my exam lol
