Are negative-feedback loops really the body’s default setting? 🤔 How do Le Chatelier’s principle and the bicarbonate buffer keep your blood pH rock-steady at 7.4? In this Jack Westin MCAT Podcast episode, Mike and Molly break down the science of homeostasis and chemical equilibrium—then show you exactly how to apply those concepts on test day and in medicine.

🔑 What you’ll learn

- Dynamic vs. static homeostasis—and why “set points” constantly shift

- Positive-feedback mechanisms (oxytocin, prolactin, estrogen, clotting) vs. negative feedback

- The RAAS pathway & ACE inhibitors for blood-pressure control

- Equilibrium constants (Keq) and why Km is the outlier

- Real-world crossover tips: lungs, kidneys, and systemic pH regulation
