Cardiovascular and Respiratory Systems: Physiology and Calculations

Understanding how the heart and lungs work together is fundamental to medicine, nursing, and health sciences, yet mastering the complex feedback loops, graphs, and mathematical formulas can feel overwhelming. This text-based course simplifies these vital systems, breaking down complex physiological laws into clear, digestible written concepts. You will develop a solid foundational understanding of cardiopulmonary physiology, learning how to interpret pressure-volume loops, calculate cardiac output, analyze respiratory compliance, and apply these concepts to real-world clinical scenarios. What you'll learn: 1. Understand the core anatomy and physiological principles governing the cardiovascular and respiratory systems. 2. Master key physiological calculations, including cardiac output, stroke volume, alveolar ventilation, and gas exchange equations. 3. Interpret essential clinical graphs, such as pressure-volume loops and oxygen-hemoglobin dissociation curves. 4. Apply theoretical knowledge to analyze introductory clinical case scenarios and practical problem-solving exercises. 5. Explore modern digital health biomarkers, including heart rate variability (HRV) and pulse oximetry (SpO2) dynamics. 6. Practice self-assessment through targeted multiple-choice questions designed to reinforce key concepts. The course begins with foundational definitions of cardiopulmonary anatomy and blood flow mechanics before progressing to advanced gas laws, pressure-volume relationships, and calculations. You will wrap up by reading through structured clinical case studies and self-testing your knowledge with written practice scenarios. This course is designed for beginners, pre-med students, nursing students, and healthcare enthusiasts looking for a clear, structured introduction to cardiopulmonary physiology. No advanced medical background is required. Start reading today to build a confident working knowledge of how the heart and lungs function together.
