Cardiovascular | Fundamentals of Blood Pressure

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this cardiovascular physiology lecture, Professor Zach Murphy presents the fundamentals of blood pressure, explaining how it’s generated, regulated, and measured—laying the groundwork for understanding normal physiology and common clinical conditions. We begin with the core definitions: systolic and diastolic pressure, pulse pressure, and mean arterial pressure (MAP), followed by a breakdown of the physiological determinants—cardiac output (CO) and total peripheral resistance (TPR). Zach then introduces Poiseuille’s Law to explain how vessel radius, length, and viscosity influence resistance and pressure, helping you connect fluid dynamics to systemic circulation. You’ll also learn how blood pressure is measured in clinical practice using a sphygmomanometer and the detection of Korotkoff sounds, clarifying the physical basis for identifying systolic and diastolic pressures during auscultation.
