- 7. Multiple ChoiceWhich of the following define diastole and systolesystole is the contraction of the heart and diastole is the relaxation of the heartdiastole is the contraction of the heart and systole is the relaxation of the heartdiastole and systole are both contractions of the heartdiastole and systole are both relaxation phases of the heart
- 8. Multiple ChoiceWhat is ECG?electrocardiograma tool that collects electrical changes in the heart musclewill detect any abnormal rhythm of the heartall of the above

- 11. Multiple ChoiceThe lining of the chambers of the heart is called themyocardiumepicardiumendocardiumpericardium
- 12. Multiple ChoiceFreshly oxygenated blood is delivered to the _____________ and then it passes into the __________ to be pumped to the entire body.right ventricle; right atriumleft ventricle; left atriumleft atrium; left ventricleright atrium; right ventricle
- 13. Multiple ChoiceInto which chamber of the heart do the pulmonary veins deliver blood?left ventricleright atriumleft atriumright ventricle
- 14. Multiple ChoiceThe most muscular chamber of the heart is theleft ventricleleft atriumright atriumright ventricle
- 15. Multiple ChoiceWhich of the following is a difference between cardiac muscle and skeletal muscle?unlike skeletal muscle cells, cardiac muscle cells do not rely on an influx of calcium ions for depolarizationunlike skeletal muscle, cardiac muscle is not striatedunlike skeletal muscle, cardiac muscle does not use a sliding filament mechanism for contractionunlike skeletal muscle cells, cardiac muscle cells can be autorhythmic
- 16. Multiple ChoiceThe role of the atrioventricular node (AV node) is toinitiate a sinus rhythmconduct impulses to the sinoatrial node (SA node)initiate ventricular depolarizationslow down impulses so that the atria can contract to fill the adjacent ventricles with blood
