1. The volume of blood pumped out of the heart from one ventricle during one contraction: Stroke Volume (SV)
2. The rapid depolarization phase of the action potentials of myocardial contractile cells is due to which ion(s)?: Na+ only
3. The volume of blood in the ventricle available to be pumped out of the heart during one contraction: End- diastolic volume (EDV)
4. The volume of blood left in the ventricle after it contracts: End- systolic volume (ESV)
5. The volume of blood ejected from each ventricle during a contraction: -
Stroke volume (SV)
6. What happens when calcium binds to troponin?: Tropomyosin is pulled away from the myosin-binding site on actin.
7. The driving force for blood flow is a(n) ________ gradient.: pressure
8. Which would NOT cause an increase in blood pressure?: a decrease in cardiac output
9. Match the name of the wave with the correlated event: ventricular depolarization: QRS complex
10. The function of transverse tubules is to: rapidly conduct action potentials to the interior of the muscle fiber.
11. Which is greater: A) blood pressure when the peripheral vessels constrict
B) blood pressure when the peripheral vessels dilate: A) blood pressure when the peripheral vessels constrict
12. The P wave of an ECG corresponds to: depolarization of the atria
