Cardiovascular Physiology: Foundations of the Heart and Circulation

Understanding how the human heart and circulatory system function is crucial for anyone entering the healthcare, sports science, or biological fields. This text-based course breaks down complex cardiovascular mechanisms into clear, accessible concepts. You will transition from basic anatomical knowledge to a deep, functional understanding of how the cardiovascular system regulates blood flow, adapts to stress, and maintains homeostasis. Through detailed written explanations and self-assessment questions, you will build a solid foundation in cardiac mechanics and hemodynamics. What you'll learn: - Understand the phases of the cardiac cycle and how they correlate with heart sounds and pressure changes. - Analyze pressure-volume loops to evaluate cardiac output and ventricular function. - Interpret the foundational principles of electrocardiograms (ECGs) and the cardiac conduction system. - Explain hemodynamics, blood pressure regulation, and the mechanics of blood flow through vessels. - Examine jugular venous pulse (JVP) waveforms and their clinical significance in cardiovascular health. - Apply your knowledge to clinical scenarios through structured written review questions and practice scenarios. We begin with essential terminology and the basic anatomy of the cardiac conduction system before moving into mechanical principles like hemodynamics and pressure-volume relationships. This course is designed for beginning medical students, nursing students, biology majors, or healthcare enthusiasts. No advanced prior background in cardiology is required.
