Q

what is a coronary angioplasty?

A

insertion of a small balloon catheter into the lumen of the coronary artery; the balloon is inflated to flatten the obstructing plaque against the wall and increase the size of the lumen improving blood flow

25
Q

how are the unpaired visceral branches described?

A

they come straight off the aorta and will supply a visceral structure

26
Q

what are the 3 unpaired visceral branches?

A

mediastinal artery, esophageal artery, and pericardial artery

27
Q

what does the mediastinal artery supply?

A

the lymph nodes of the posterior mediastinum

28
Q

what does the esophageal artery supply?

A

the middle 1/3 of the esophagus

29
Q

what does the pericardial artery supply?

A

small branches to the pericardium

30
Q

what are the paired lateral visceral branches?

A

the right and left bronchial arteries

31
Q

what are the bronchial arteries responsible for?

A

supplying the the structures of the hilum of the right/left lung

32
Q

what are the paired segmental parietal branches?

A

the posterior intercostal arteries

33
Q

what is the first thing the posterior intercostal arteries are going to branch?

A

the dorsal branch

34
Q

what does the dorsal branch supply?

A

back musculature

35
Q

after the posterior intercostal artery produces a dorsal branch, what will it produce next?

A

a collateral branch

36
Q

after the posterior intercostal artery makes a collateral branch, what does it produce next?

A

a lateral cutaneous artery

37
Q

what is our third and final source for mammary arteries (not from the perforating branches of the internal thoracic and not the lateral mammary arteries from the lateral thoracic artery)?

A

we get a lateral mammary branch from the lateral cutaneous artery (which is a branch of the posterior intercostal artery

38
Q

what is the last branch that we have before the aorta goes through the thoracic diaphragm?

A

the superior phrenic artery

39
Q

what are the phrenic arteries and where do they come from?

A

musculophrenic artery (from the internal throacic artery), pericardiacophrenic artery (from internal throacic artery), and the superior phrenic artery (from the descending throacic aorta)

40
Q

what are the branches of the right pulmonary artery?

A

superior lobar artery, middle lobar artery, and inferior lobar artery

41
Q

what are the branches of the left pulmonary artery?

A

superior lobar artery and inferior lobar artery

42
Q

What branches from the lobar arteries?

A

segmental arteries

43
Q

what is a pulmonary embolism?

A

obstruction of a pulmonary artery by an embolus, such as a blood clot, fat globule, or air bubble

44
Q

what do the pulmonary veins begin as?

A

intersegmental veins between the bronchopulmonary segments

45
Q

what do the pulmonary arteries follow?

A

the airway

46
Q

what do the pulmonary veins empty into?

A

the left atrium

47
Q

what do the pulmonary veins carry?

A

oxygenated blood

48
Q

where is the coronary sinus found?

A

posterior aspect of the heart

49
Q

what does the coronary sinus drain?

A

great, middle, and small veins

50
Q

what does the coronary sinus empty into?

A

the right atrium of the heart

51
Q

what does the small cardiac vein travel with?

A

the right marginal artery

52
Q

what does the middle cardiac vein travel with?

A

the posterior interventricular artery

53
Q

what does the great cardiac vein travel with?

A

the anterior interventricular artery (anteriorly) and the circumflex artery (posteriorly)

54
Q

what is the route of the anterior cardiac veins?

A

they come off the anterior part of the heart (usually on the right ventricle) and they cross over the right anterior ventricular groove, and empty directly into the right atrium

55
Q

what does the azygous vein drain and where is it sitting?

A

drains the right side posterior intercostal vein- sitting on the right side

56
Q

what does the azygous vein empty into?

A

the superior vena cava

57
Q

what drains the left posterior intercostal veins from the lower posterior thoracic wall?

A

the hemiazygous vein

58
Q

what drains the the left posterior intercostal veins from the upper posterior thoracic wall?

A

accessory hemiazygous vein

59
Q

what does the thoracic duct originate as?

A

the cisterna chyle

60
Q

where does the thymus sit?

A

in the anterior superior mediastinum
