The Cardiovascular, Pulmonary, and Renal (CPR) course is a 12-week integrated systems course for first-year medical students that examines how these organ systems work together to maintain physiological homeostasis.
Building on foundational concepts introduced in Molecules to Mechanisms (M2M), students apply principles of molecular and cellular physiology, membrane transport, tissue structure, and pharmacologic mechanisms to understand normal organ function. Students will examine how the cardiovascular, pulmonary, and renal systems coordinate to maintain physiologic homeostasis.
The course emphasizes the relationships between cardiac output, pulmonary gas exchange, and renal regulation of fluid, electrolytes, and acid–base balance in sustaining volume homeostasis and tissue perfusion (oxygen and nutrient delivery) blood pressure. Students also analyze how disruptions in these integrated mechanisms lead to common pathophysiologic conditions affecting the heart, lungs, and kidneys.
Particular attention is given to sodium and water regulation, highlighting how nephron transport processes link renal function with cardiovascular hemodynamics and pulmonary fluid balance. Interactive learning activities reinforce these connections and support the development of early clinical reasoning grounded in foundational science.
