Let's apply these key concepts to some common pathophysiological processes: Clinical pathophysiology made ridiculously simple

| Disease | Normal Physiology | The Broken Rule | Ridiculously Simple Phrase | | :--- | :--- | :--- | :--- | | | Blood vessels have normal tone. | Bacteria trigger massive inflammation. All blood vessels dilate at once. | "The pipes turned into fire hoses. No pressure." | | Cirrhosis | Liver filters toxins, makes protein. | Scar tissue blocks blood flow through the liver. | "A traffic jam in the portal vein.
