Cardiovascular | Blood Pressure Regulation | Hypotension

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this cardiovascular physiology lecture, Professor Zach Murphy covers the mechanisms of blood pressure regulation, with a specific focus on the body’s response to hypotension. This session integrates short-term neural control and long-term hormonal regulation, providing a complete understanding of how the body maintains perfusion under stress. We begin by breaking down the baroreceptor reflex, highlighting how mechanoreceptors in the carotid sinus and aortic arch detect changes in arterial pressure and trigger autonomic adjustments in heart rate, contractility, and vascular tone. From there, we examine the roles of the sympathetic nervous system, adrenal medulla, and vasoconstrictive hormones in rapidly restoring pressure during acute hypotensive events. Zach then introduces the renin-angiotensin-aldosterone system (RAAS) and antidiuretic hormone (ADH) pathways as slower-acting mechanisms that regulate blood volume and systemic resistance. These long-term strategies are key to maintaining homeostasis in settings like chronic hypotension, volume depletion, and orthostatic changes.
