Q

Explain pulmonary circulation

A

Blood goes into the RA from the vena cava, blood then goes into the RV, the right ventricle forces blood through the pulmonary artery to the lungs, gas exchange occurs in the lungs, oxygenated blood returns to the left side of the heart

Q

Explain systemic circulation

A

Blood comes into the LA from the lungs, it then goes to the left ventricle, the left ventricle contacts and blood is forced to all body tissues where has exchange occurs

26
Q

Where are the AV walked located?

A

Between the atria and ventricles

27
Q

The job of the AV valves is to

A

Prevent back flow into the atria when the ventricles contract

28
Q

The right AV valve is

A

The tricuspid valve (3 flaps)

29
Q

The left AV valve is called the

A

Bicuspid or mitral valve (2 flaps)

30
Q

What anchors the flaps to the walls in the ventricles

A

Chordae Tendineae

31
Q

When the heart is relaxed

A

Blood is filling the chambers and the tri and bicuspid are open

32
Q

When the ventricles are filled and are contacting the AV valves

A

Are closed

33
Q

When the heart is contracting

A

Blood is leaving the ventricles and the SL valves are open

34
Q

Where is the pulmonary SL valve

A

At the base of the pulmonary trunk

35
Q

The aortic SL valve is

A

At the base of the aorta

36
Q

The SL valves are closed when the heart

A

Relaxes and begins to fill again

37
Q

What are the heart sounds?

A

A lub-dub, there sounds indicate the valves closing

38
Q

What is the lub?

A

The AV valves closing

39
Q

What is the dub sound?

A

The SL valves closing

40
Q

What sound do leaky valves make?

A

A swishing sound

41
Q

What is the swishing sound called

A

A heart murmur

42
Q

Explain cardiac circulation

A

Coronary arteries take blood from the heart to the heart muscle, after gas exchange blood returns by the cardio vein into the right atrium

43
Q

Decreased oxygen to the heart muscles that cause pain

A

Angina

44
Q

What are the 3 ways to un-block a coronary artery?

A

Angioplasty, stents, and coronary bypass surgery

45
Q

How is an angioplasty done?

A

A guide wire is inserted through the femoral artery and guided into the blocked artery, the balloon is inflated to compress the plaque against the artery wall to open the lumen, the balloon is then deflated

46
Q

How does a stent work?

A

A guide wire is inserted into the lumen of the blocked artery, a metal stent is opened in the lumen to open the artery, the wire is removed but the stent remains and keep the lumen open

47
Q

What is coronary bypass surgery?

A

It creates a pathway around the blocked part of your artery, a leg vein is removed and used as a graft around the blocked artery, the blocked artery is bypassed and blood will now flow through the grafted vessel

48
Q

How impulses travel through the heart muscle to make it contract and empty each chamber

A

Conduction system

49
Q

Where is the SA node?

A

In the right atrium

50
Q

What does the SA node do?

A

Starts each heartbeat and sets the pace for your heart

51
Q

What picks up the signal and sends it to the AV bundle, bundle branches, and the Purkinje fibers

A

AV nodes

52
Q

What does an EKG do?

A

It measures the electrical impulses going through the heart and graphs it

53
Q

What causes heart blocks?

A

Damage to the AV nose

54
Q

Rapid uncoordinated shuttering of the ventricles

A

Fibrillation

55
Q

Slow heart rate, less than 60 beats per minute

A

Bradycardia

56
Q

Fast heart rate, more than 100 beats per minute

A

Tachycardia

57
Q

When a machine delivers electrical energy to the heart muscle to restore normal rhythm and restart the SA node

A

Defibrillation

58
Q

75 beats per minute

A

Normal cardiac cycle

59
Q

Heart relaxed and filling through the atria to the ventricles

A

Diastole

60
Q

Heart is contracting and the ventricles are emptying

A

Systole

61
Q

How do you calculate cardiac output?

A

HR•SV

62
Q

The volume of blood pumped out by a ventricle with each heartbeat

A

Stroke volume

63
Q

How fast your heart beats in a minute

A

Heart rate

64
Q

What factors effect heart rate?

A

Physical or emotional stress, hormone levels, ions like calcium and potassium levels, age, gender, exercise, and body temp
