While shopping at your local drugstore, you stop at the blood pressure machine. It measures your blood pressure as 115/75 (good—that's healthy!). This number means that
A. arterial pressure is 115 mm Hg when the ventricles contract and 75 mm Hg in between ventricular contractions. B. arterial pressure is 75 mm Hg when the ventricles contract and 115 mm Hg in between ventricular contractions. C. arterial pressure is 115 mm Hg when the atria contract and 75 mm Hg in between atrial contractions. D. your sinoatrial node generates a 115 mV signal and your atrioventricular node generates a 75 mV signal. E. your sinoatrial node generates a 75 mV signal and your atrioventricular node amplifies this to a 75 mV signal.
