In this cardiovascular physiology lecture, Professor Zach Murphy dives into cardiac output (CO)—a critical measure of the heart’s performance and a central determinant of tissue perfusion. This lecture explains how cardiac output is calculated, regulated, and applied in physiology and clinical settings. We begin by defining cardiac output as the product of heart rate (HR) and stroke volume (SV), then explore the major factors that influence each component. You’ll learn how preload, afterload, and contractility affect stroke volume, and how autonomic tone modulates heart rate. The Frank-Starling mechanism, inotropic effects, and venous return dynamics are all discussed in detail to help solidify your understanding of how the body adjusts CO to meet changing demands.
