It measures your blood pressure as 115/75 (good-that's healthy!). This number means that O arterial pressure is 115 mm Hg when the ventricles contract and 75 mm Hg in between ventricular contractions. O your sinoatrial node generates a 115 mV signal and your atrioventricular node generates a 75 mV signal. O your sinoatrial node generates a 75 mV signal and your atrioventricular node amplifies this to a 75 mV signal. arterial pressure is 115 mm Hg when the atria contract and 75 mm Hg in between atrial contractions.

arterial pressure is 75 mm Hg when the ventricles contract and 115 mm Hg in between ventricular contractions. QUESTION 46 To become bound to hemoglobin for transport in a mammal, atmospheric molecules of oxygen must cross O zero membranes –oxygen binds directly to hemoglobin, a protein dissolved in the plasma of the blood one membrane-that of the lining in the lungs-and then bind directly to hemoglobin, a protein dissolved in the plasma of the blood two membranes-in and out of the cell lining the lung-and then bind directly to hemoglobin, a protein dissolved in the plasma of the blood four membranes-in and out of the cell lining the lung, in and out of the endothelial cell lining an alveolar capillary and then bind directly to hemoglobin, a protein dissolved in the plasma of the blood five membranes-in and out of the cell lining the lung, in and out of the endothelial cell lining an alveolar capillary, and into the red blood cell-to bind with hemoglobin Honorlock Browser Guard" app.honorlock.com is sharing your screen.
