4. Column 1, #1 What is the name of the circuit that pumps blood out to the body tissues and back to the heart? Systemic circuit

5. Column 1, #2 Pulmonary circuit. What is the name of the circuit that pumps blood out to the lungs and back to the heart?

6. Column 1, #3 Which chamber pumps blood out to the body systems? left ventricle.

7. Column 1, #4 Which chamber receives deoxygenated blood from the body? Right atrium

8. Column 1, #5 Left atrium. Which chamber receives oxygenated blood from the pulmonary circuit?

9. Column 2, #1 Atrioventricular (AV) valves. What is the name of the structures that ensure one-way blood flow from the atria to the ventricles.

10. Column 2, #2 Endocardium. What is the term for the inner lining of the pumping chambers of the heart?

11. Column 2, #3 Superior and inferior venae cavae. What is the name of the large veins that carry the systemic blood back to the right atrium?

12. Column 2, #4 Chordae tendinae. What is the name of the structures that anchor the cusps of the AV valves?

13. Column 2, #5 Which layer of the epicardium covers the heart surface? Visceral pericardium.

14. Column 3, #1 Which type of cardiac cells provide the pumping action and make up 99% of all cardiac muscle cells? Contractile cells.

15. Column 3, #2 Which type of cardiac cells generate and spread the action potential? Conducting cells (non-contractile cells).

16. Column 3, #3 On an EKG, which component represents ventricular depolarization? QRS complex.

17. Column 3, #4 T wave. On an EKG, which component represents ventricular repolarization?

18. Column 3, #5 Cardiac AP has a long plateau phase. Cardiac muscle has a long, slow twitch. Cardiac muscle has a long refractory period, which prevents tetanus. What are some of the differences between cardiac and skeletal muscle cells?

19. Column 4, #1 What is another name for the contraction phase of the cardiac cycle? systole.

20. Column 4, #2 Diastole. What is another name for the relaxation phase of the cardiac cycle?

21. Column 4, #3 “lubb” Identify the first heart sound caused by the closing of the AV valve.

22. Column 4, #4 Lowers heart rate and stroke volume. What effect does parasympathetic innervation have on heart rate and stroke volume?

23. Column 4, #5 What effect does sympathetic innervation have on heart rate and stroke volume? Raises heart rate and stroke volume.

24. Column 5, #1 What is arteriosclerosis? The hardening and thickening of the walls of smaller arteries.

25. Column 5, #2 What is atherosclerosis? The formation of plaques in the inner wall of blood vessels.

26. Column 5, #3 Arrhythmia. What is another term for a disturbance in the rhythm of the cardiac cycle?

27. Column 5, #4 Coronary heart disease. Which condition results from arteriosclerosis and atherosclerois?

28. Column 5, #5 Which term describes a slowing in the heart rate (below 60 bpm)? Brachycardia.

29. Bonus Question 1: Describe the series of events that allows the ear to detect sound.

30. Bonus Question 2: (a) Describe the series of events that allows you see an image. (b) What is the name of the structure in the brain that perceives the image and flips it right-side up.
