How the Heart Contracts - Step by Step
Let's dive into the cardiac action potential and how it results in the contraction of the heart. We'll talk about the signal that starts at the SA node and spreads throughout the heart. We'll also get into the phases of depolarization, the plateau, and repolarization and how calcium release results in muscle contraction. Get my Cardiac Cycle ...

💓 Heart Valves: The Gatekeepers of Circulation 💓 Your heart has four valves, ensuring blood flows in the right direction with every beat. These valves open and close with precision, preventing backflow and keeping circulation efficient. 🔹 The Four Heart Valves: Mitral Valve 🫀 – Controls blood flow from the left atrium to the left ventricle. Aortic Valve 🔄 – Regulates blood flow from the left ventricle into the aorta. Tricuspid Valve 🫀 – Directs blood from the right atrium to the right vent
