Ready to sharpen your understanding of the respiratory system? In this Clinical Adventurer episode, we take you on a guided tour from fetal lung development to the complex mechanics that keep you breathing. We’ll break down the roles of surfactant, the key differences between upper and lower airways, and the unique features of pulmonary circulation. You’ll get clear, bedside-relevant insights into lung volumes, compliance, airway resistance, and how your body controls breathing through neural and chemical signals. Plus, we’ll cover what happens when things go wrong — from hypoventilation to pulmonary hypertension. This is the no-fluff, clinical deep dive you’ve been looking for.
