| A | B |
| stretch receptors in aortic arch and carotid sinus that assist with blood pressure control | baroreceptors |
| volume of blood ejected from the left ventricle in one minute | cardiac output |
| pressure produced by venous blood in the right atrium | central venous pressure |
| structures that are sensitive to the pH, CO2, and oxygen in the blood and regulate the sympathetic nervous system | chemoreceptors |
| ability of cardiac tissue to transmit an electrical stimulus from cell to cell within the heart | conductivity |
| ability of cardiac tissue to stretch as a single unit and recoil | contractility |
| stage when positive ions move inside the myocardial cell membranes and the negative ions move ouside | depolarization |
| conduction disorder that results in an abnormally slow or rapid heart rate or one that does not proceed through the conduction system in the usual manner | dysrhythmias |
| stage during diastole when positive ions predominate outside myocardial cell membranes and negative ions predominate inside | polarization |
| stage when ions realign themselves in their origianl position and wait for an electrical impulse | repolarization |
| amount of blood pumped per contraction of the heart | stroke volume |
