Q

32
Q

Where is the heart location?

A

Left of the midline in the thoracic cavity

33
Q

What are the two layers of the pericardium?

A

Fibrous and serous pericardium

34
Q

What is the blow flow cycle?

A

Deoxygenated blood goes in the superior and inferior vena cava, into right atrium, into the right ventricle, through the pulmonary trunk through the left and right pulmonary artery. The oxygenated blood goes into the pulmonary veins into the left atrium, to the left ventricle, which goes into the aorta.

35
Q

What is the right AV valve called?

A

Triscuspid

36
Q

What is the left AV valve called?

A

Mitral valve

37
Q

What are the coords connecting the papillary muscle and the right ventricle?

A

Tendinous cords

38
Q

What are the two major arteries?

A

The right and left coronary arteries

39
Q

What is the artery on the right more in the center?

A

Posterior descending artery

40
Q

What splits off the right coronary artery?

A

Right marginal artery

41
Q

What is the artery right under the coronary artery?

A

The left circumflex artery

42
Q

What left artery is more on the back?

A

The left marginal artery

43
Q

What left artery is more towards the center?

A

Left anterior descending artery

44
Q

What vein is under the superior vena cava?

A

The anterior cardiac vein

45
Q

What is the lowest under the superior vena cava?

A

Small cardiac vein

46
Q

What is under the left atrium?

A

The great cardiac vein

47
Q

What connects most of the veins?

A

The coronary sinus

48
Q

What vein runs down the center?

A

The middle cardiac vein

49
Q

What does systole mean?

A

Contraction

50
Q

What does diastole mean?

A

Relaxation

51
Q

What is the strove volume formula?

A

SV = End-diastolic volume - End-systolic volume

52
Q

What is the formula for CO?

A

CO= heart rate (HR) x Stroke volume (SV)

53
Q

What is the cardiac resting potential?

A

-90mV maintained by K+ leakage

54
Q

What is depolarization caused by?

A

Influx of Na+ through fast channels at 0 then influx of Ca2+ at -40

55
Q

What happens during the resting phase?

A

K+ rectifier opens and Ca and Na close

56
Q

What happens during depolarization?

A

Na open and Ca open

57
Q

What happens during early repolarization?

A

K efflux and Na close

58
Q

What happens during plateau phase?

A

K and Ca equilibrium

59
Q

What happens during repolarization?

A

Ca close and K influx

60
Q

What is the conduction pathway?

A

SA node - AV node - AV bundle - left and right bundle branch - purkinje fibers

61
Q

What is the output of an ECG machine called?

A

Electrocardium

62
Q

What happens during the p wave?

A

Depolarization of atria

63
Q

What happens during the PR interval?

A

Delay of AV node to allow filling of ventricle

64
Q

What happens during the QRS complex?

A

Depolarization of ventricles

65
Q

What covers the atria repolarization

A

The QRS complex

66
Q
