CPR Angiology Flashcards
Which major coronary artery does more to supply the conductance system of the heart?
What branch of that major artery is so vital?
left coronary artery
anterior interventricular artery
Which side has the brachiocephalic trunk?
What comes off of the brachiocephalic trunk?
the right side
right common carotid and right subclavian arteries
What are the 2 terminal arteries of the internal thoracic artery?
Which one is medial & which one is lateral?
musculophrenic A (lateral)
superior epigastric A (medial)
What artery does the anterior intercostal artery come off of?
internal thoracic artery
What are the 3 sources of blood to the mammary tissue/gland?
Lateral mammary A (from lateral thoracic A)
Medial mammary A (from internal thoracic A)
Lateral cutaneous branches of posterior intercostal arteries
Describe path of the aorta
distal to L vent & aortic valve, travels superiorly as ascending aorta, turns LET as aortic arch & travels inferiorly as descending aorta thru thorax
When does the thoracic aorta become the abdominal aorta?
when passes thru aortic hiatus of the thoracic diaphragm & enters into abdomen
What procedure helps remove obstruction of the coronary arteries?
Coronary artery bypass graft
replace segment of coronary artery by using part of great saphenous vein or radial artery
What is a coronary angioplasty?
insertion of a small balloon catheter into lumen of coronary artery
inflate balloon to flatten obstructing plaque against wall & increase size of lumen to improve blood flow
What is a pulmonary embolism?
obstruction of a pulmonary artery by an embolus (blood clot, fat or air bubble)
passes thru vein & into R side of heart & into pulmonary arteries, limits gas exchange in that location
What are the 2 branches of the ascending aorta?
the left & right coronary arteries
Name the branches of the R coronary artery
sinuatrial nodal A conus branch atrial branch right marginal A atrioventricular nodal A posterior interventricular A R posterolateral A
What supplies the left ventricle?
posterior left ventricular A (off circumflex A)
R posterolateral A (from post IV A off R coronary A)
Name the branches of the L coronary artery
anterior interventricular A
circumflex A
What 3 arteries supply the diaphragm?
Musculophrenic A (internal thoracic A)
Pericardiophrenic A (internal thoracic A)
Superior phrenic A (descending thoracic aorta)
What cardiac vein empties directly into the right atrium without passing through the coronary sinus?
anterior cardiac veins
What vein runs with the posterior interventricular artery?
middle cardiac vein
What vein runs with the circumflex artery?
great cardiac vein
what vein runs with the right marginal artery?
small cardiac vein
what vein runs with the anterior interventricular artery?
great cardiac vein
What supplies the R atrium?
atrial branch of the R coronary artery
What supplies the interventricular septum?
interventricular septal branches
off of posterior interventricular A of R coronary A & anterior interventricular A of L coronary A
What supplies the left ventricle?
R posterolateral A from R coronary A & Posterior left ventricular A from circumflex A
What are the 2 branches of the left coronary A?
anterior interventricular A & circumflex A
What comes off of the arch of the aorta?
brachiocephalic trunk, left common carotid A & left subclavian A
axillary A
Where does the internal thoracic A come from?
left subclavian A
What is the primary blood supply to the pericardium of the heart?
pericardiophrenic A (off internal thoracic A)
What supplies the superior portion of serratus anterior m?
superior thoracic a
What supplies the intercostal muscles?
lateral thoracic A (off of axillary A)
What are the branches of the descending (thoracic) aorta?
unpaired visceral branches
paired lateral visceral branches
paired segmental parietal branches
superior phrenic A
What are the branches of the R pulmonary A?
superior lobar A
middle lobar A
inferior lobar A
What are the branches of the L pulmonary A?
superior lobar A
inferior lobar A
Where do the pulmonary veins originate?
begin as intersegmental veins btwn bronchopulmonary segments
empty into L atrium
What does the coronary sinus empty into?
into the R atrium of the heart (posterior aspect)
What are the 3 veins of the coronary sinus?
great cardiac v
middle cardiac v
small cardiac v
What joins to form the SVC?
union of R & L brachiocephalic Vs w/ azygos V (into R atrium of heart)
What does the azygos v drain?
drains posterior intercostal v from R side of posterior thoracic wall
travels superiorly until crossing over vertebral bodies to meet w/ SVC
What does the hemiazygos v drain?
drains posterior intercostal v from L side of lower posterior thoracic wall
What does the accessory hemiazygos v drain?
drains posterior intercostal v from L side of upper posterior thoracic wall
What makes up the IVC?
union of R & L common iliac V & travels thru abdomen via vena cava foramen of thoracic diaphragm to reach inferior R atrium
What is the thymus?
primary lymphoid organ located in the anterior superior mediastinum
replaced w/ fat after puberty
Major ducts of lymphatics
thoracic duct on left
R lymphatic duct
What drains the lymph in the breast region?
axillary lymph nodes drain 75% of breast lymph
What drains the parietal pleua?
intercostal LNs
phrenic LNs
anterior mediastinal LNs
posterior mediastinal LNs
What drains the visceral pleura of the lungs?
superficial lymphatic plexus of lungs drains into bronchopulmonary lymph nodes (get to thoracic lymph nodes)
