Answer 1

17. d) subclavian area....pacemakers is implanted position for electrical devices in heart

18.b) repair the aortic arch

19. a) following a myocardial infarction

20. greater sephenous vein is large venous blood vessel running near the inside surface of the leg from ankle to groin.

this vein sometimes stripped out of the leg to eliminate varicose veins

it is used for best source of graft in coronary bypass surgery.this vein collects deoxygenated blood from medial side of the foot and medial & anterior side of the lower leg.

21. sutures and stainless steel wires are used for closing of sternum.

wire sutures are placed around the manubrium and four are placed around the edge of sternum.

22. a aneurysm is may occur in any blood vessel., but mostly occur in artery than veins. shape of aneurysm is fusiform or saccular, which helps to identify the true aneurysm in blood vessels. in fusiform aneurysm is bulges or balloon out on all side of the blood vessels. mostly seen in abdominal aortic and cardiac region.

23. saccular aneurysm is bulges or balloon out only on one side of the blood vessels. this is mostly seen in arteries at the base of the brain.

24. cardiac cycle is defined as the complete sequence of events in the heart from the beginning of one beat to the beginning of following beat. a complete heart beat including systole and diastole.

25. ventricle systole is defined as contraction of the ventricles forcing blood into the aorta and pulmonary artery.

26. diastole is the phase of heartbeat when the heart muscle relax  and allows the chambers to fill with the blood.

27. pericardium it is double layered ,it contains sacs that is pericardium sac...this sac is 2 layers ...serous layer and fibrous layer.

28. heart muscle is also called cardiac muscle or myocardium.

29. chordae tendineae muscle.
