He opened his eyes. "The jugular venous pulse is a pressure waveform, sir, reflecting right atrial dynamics," he began. And then he told the story. Not like a student reciting a textbook, but like a witness describing a scene.
Rohan just pointed to his head. "I told you a story." gk pal physiology
Rohan held up the battered blue-and-green book. "Don't read it. Live in it. The action potential isn't a graph. It's a wave of panic spreading through a city. The nephron isn't a diagram.
