Great lecture and even better video, well organized and easy to follow. You mentioned BP & SVR often get confused, but does BP have an effect on the amount of SVR you'd feel? (Will hypertension increase Dynes in the arteries?)

[@EmPoisonPharmD]

Thank you Sabo, good question. While BP and and SVR are not the same, SVR is a component of BP. Consider blood pressure to be be the net sheering force between the constricted artery vessel walls (SVR) and the volume of blood being injected into the system (cardiac output). Increased BP could be from an increased cardiac output or from increased SVR or both. So, I guess yes, if your BP is high, it could be because your vessels are constricted (the amount of dynes you feel), or it could be due to a large increase in cardiac output, despite your dynes being unchanged. I hope that clarifies. Thanks for watching.
