1 Cardiac Cycle This quiz will require you to apply concepts from the cardiac cycle and control of blood flow. Click here to see the instructions

2 How It Works The program will display a question at the top of each screen. Click on the button with the correct answer At the end of the game, it will show you how many right and wrong answers you chose. Click here to begin the game Help! Nothing happened!

3 Troubleshooting If you weren’t able to begin the game, it’s probably because your PowerPoint security settings are set too high. Here’s what to do: –Open PowerPoint and choose ‘Options’ from the ‘Tools’ menu –Click on the ‘Security’ tab and on ‘Macro Security’ in the lower half of the screen. –Set Macro security at ‘Medium’ and close PowerPoint. Click the button below to go back to the Main Menu, and re-open this quiz. The computer should ask you whether you want to enable macros. Tell it to enable them. Click here to go to the main menu and restart the quiz

4 After blood enters the right atrium, it goes through the: Bicuspid valve Inferior vena cava Mitral valveCoronary arteries Pulmonary trunk Tricuspid valve

5 The left atrium receives blood from the: Right atrium Left ventricle Hepatic portal veinSystemic arteries Lungs Superior vena cava

6 The bicuspid valve is between: Left atrium and right atrium Left atrium and Left ventricle Left atrium and Right ventricle Superior vena cava and Left atrium Pulmonary veins and Left atrium Right atrium and Right ventricle

7 The pulmonary circuit runs from the: Pulmonary vein to aorta Right atrium to Pulmonary semilunar valve Left atrium to left ventricle Pulmonary trunk to the Left atrium Right atrium to Iliac artery Left ventricle to Cerebral arteries

8 In the pulmonary circuit, you find the blood with the least Oxygen in the: Pulmonary veins Pulmonary arteries Pulmonary venulesInferior vena cava Left atrium Pulmonary capillaries

9 Red blood cells in pulmonary capillaries: Pick up O2, Drop off CO2 Pick up CO2, Drop off O2 Pick up O2, Pick up CO2 Secrete erythropoietin Divide to form reticulocytes Drop off O2, Drop off CO2

10 Systole happens when: Atria contract Semilunar valves close AV valves open The heart is relaxing The heart is filling with blood Ventricles contract

11 During diastole: The heart is relaxed Blood flows into the aorta The AV valves are closed The semilunar valves Are open Blood flows though The semilunar valves The ventricles contract

12 The ‘pacemaker’ cells that start a heart beat are in: The atrial septum The left ventricle The right atrium The papillary muscles The superior vena cava The interventricular septum

13 The pacemaker is called: The node of Ranvier The semilunar valve The papillary muscle The chordae tendinae The SA node The AV node

14 The cells in the SA node fire because: A neurotransmitter attaches to them Ca2+ leaks into the cells The SNS is activated Their acetylcholine receptors are stimulated The cells next to them have fired They receive an electrical impulse

15 When cardiac muscle cells have depolarized, they: Open their Na+ channels Close Ca2+ channels Remain at resting potential Repolarize Remain depolarized for a while Close K+ channels

16 The P wave indicates: Ventricular repolarization Atrial hyperpolarization Ventricular hypopolarization Atrial repolarization Atrial depolarization Ventricular depolarization

17 The T wave indicates: Ventricles relaxing Atria contracting Ventricles contracting Ventricles repolarizing Atria repolarizing Atria depolarizing

18 If the Bundle of His is damaged, you see: A shortened PR interval High, pointed T wavesA prolonged PR interval No QRS complexes Multiple rapid P waves A widened QRS complex

19 The first heart sound is caused when: Ventricles relax ANF is secretedThe heart is empty Ventricles repolarize AV valves close Semilunar valves close

20 If the semilunar valves didn’t close properly, you would hear: No heart sounds A murmur during systole No first heart soundA murmur during diastole A murmur throughout the heartbeat A murmur in the carotids

21 If heart rate increases, Cardiac Output will: Depend on peripheral resistance Decrease and then increase Decrease Not be affected Increase Depend on blood pressure

22 Peripheral Resistance is: The amount of blood pumped out of the heart in one minute How high blood would rise in a cannula inserted into the artery the amount of blood entering a tissue divided by the number of capillaries A person’s ability to maintain blood pressure when conditions change How hard it is to push blood through the blood vessels The pressure blood exerts against the walls of the arteries

23 If Blood Pressure goes down: Low BP will cause low PR The body can raise it by increasing CO The body will activate the PNS PR and CO will both decrease The body can fix it by lowering PR CO will decrease

24 To increase peripheral resistance: Vasoconstrict arterioles Vasodilate arteriolesIncrease heart rate Increase blood pressure Vasodilate capillaries Vasoconstrict capillaries

25 When blood volume increases: SV increases CO decreases PR decreasesHR increases BP decreases PR increases
