Preload, Afterload, Contractility & Frank–Starling

Today I cover a huge topic 'Control of Cardiac Output & Pressure." This used to be one big learning objective with 4 subsections that I will go through today. Frist I define and describe the classic terms of preload, afterload and contractility (01:19). Then I delve into the frank starling mechanism (12:34). Followed by a long look at the Guyton Curves (16:02) and the LV Pressure-Volume Loop (28:38). At the end I have some time to look at the past SAQs (34:04). This is a very diagram heavy topic and I highly recommend reviewing these diagrams in detail in preparation for the exam. Next episode I will go through 'Regional Circulation.' Thanks for listening! As always if you have any feedback let me know
