ductus arteriosus
|
between pulmonary trunk(L pulmponary artery) and arch of aorta (distal to L subclavian)
replaced by ligamentum arteriosum in adults |

|
foramen ovale
|
between atria
replaced by fossa ovalis |
|
|
ductus venosus
|
goes from umbilical vein to inferior vena cava to bypass liver
replaced by ligamentum venosum |
|
|
umbilical vein
|
carries oxygenated blood from placenta to fetus
replaced by ligamentum teres hepatis (round ligament) |
|
|
umbilical artery
|
carries deoxygenated blood from the fetus to the placenta
replaced by medial umbilical ligament |
|
|
what pierces the central tendon of the diaphragm via the caval opening?
|
inferior vena cava and R phrenic nerve
|
|
|
between which two structures does the coronary ligament run?
|
liver and the diaphragm
|
|
|
where are pectinate muscles found?
|
in the right atrium
|
|
|
coronary sulcus
|
groove between atria and ventricles; contains part of the circumflex branch of the left coronary artery
|
|
|
what do the papillary muscles and chordae tendinae do?
|
they both keep the AV valves from inverting
|
|
|
from which main artery does the anterior interventricular A branch?
|
Left coronary artery
|
|
|
what are the main venous drainage routes for the heart?
|
veins into coronary sinus
veins into heart chambers great cardiac vein middle cardiac vein |
|
|
does the superior vena cava have a valve when it goes down into the right atrium?
|
no
|
|
|
where does the L coronary artery come from?
|
ascending aorta
|
|
|
which vessels does the coronary sinus recieve?
|
middle, great, and oblique cardiac veins
left marginal vein left posterior ventricular vein |
|
|
where does the coronary sinus drain into?
|
coronary sinus drains into right atrium
|
|
|
where does the anterior cardiac vein drain into?
|
directly into the right atrium
|
|
|
what is an aortic coarctation?
|
a narrowing of the aorta in the area where the ductus arteriosus inserts; usually just beyond the site of the origin of the left subclavian artery
this results in an enlargement of the internal thoracic artery and posterior intercostal arteries |
