Get ready for an exciting journey into the world of cardiac physiology! In this fascinating course, you'll discover how the heart works as an incredible pump, powering your entire body. We'll explore the intricate electrical system that keeps your heart beating rhythmically, utilizing the specialized pacemaker cells to the complex network of conduction pathways. You'll learn about the unique action potentials of cardiac cells and how they create the familiar ECG waveform doctors use to check your heart health. We'll dive into the mechanics of the heart, understanding how it contracts and relaxes to push blood through your body efficiently. Furthermore, you'll see how the heart adapts to different demands, like exercise or stress, through amazing mechanisms like the Frank-Starling law and touch on how the body regulates blood pressure to keep everything running smoothly. By the end of this course, you'll have a newfound appreciation for the incredible organ that keeps you alive every second of every day. Topics: Cardiac Anatomy, Cardiac Output, Regulation, Frank-Starling, Baroreceptor Reflex, Bainbridge Reflex, Microcirculation, EKG.
