| Bundle of His, Bundle Branches, and Purkinje System are _________ cells. | |
| Amount of blood ejected by the ventricles. | |
| The right and left side of the heart are two pumps in ___________. | |
| In neurons, the first cell to depolarize is the ______ cell to repolarize. | |
| An increase in _________ is a compensation for heart failure where sympathetic stimulation of veins push more blood back to the heart. | |
| Autonomic control that decreases heart rate and conduction. | |
| Aortic ______ is when the aorta narrows and ventricles have to generate pressure that is larger than normal. | |
| Counting the boxes between R waves, multiplying by 0.04s, taking an inverse, and multiplying by 60 is way to calculate ______ from an EKG. | |
| Autonomic control that innervates only nodal cells and only controls heart rate. It does it through acetylcholine binding to muscarinic receptors. | |
| Preload or Afterload: Pressure that the ventricles need to have in order to eject blood. | |
| In heart cells, the last cell to depolarize is the ______ cell to repolarize. | |
| Autonomic control that increases heart rate, conduction, and contractility. | |
| a, c or v wave: atria contracting and pushing blood into the ventricles. | |
| There is a decrease in __________ in heart failure. | |
| These cells set the heart rate at 25-40 beats/min if the AV node fails | |
| This node sets the heart rate at 40-55 beats/min if the SA node fails. | |
| These valves shut at the beginning of Diastole. S2. | |
| Systole or Diastole: Isovolumic contraction, Ventricular Ejection | |
| What type of Calcium channel is open in the slow depolarization of the Pacemaker action potential? | |
| This channel in the pacemaker action potential opens when the membrane becomes more negative and does not inactivate. | |
| An increase in Reynolds number results in increased chance of ________ flow. | |
| Autonomic control that acts on nodal cells, ventricular muscles, and smooth muscles surrounding blood vessels. | |
| Systole or Diastole: Isovolumic relaxation, Filling of Ventricles, Atrial Contraction | |
| Name an electrical event that is not detected on an EKG. | |
| This organ gets the most flow per gram tissue because it is a filtration system. | |
