what nerve passes near the pericardial sac?
phrenic nerve

path takes it between subclavian A and V
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

does the superior vena cava have a valve when it goes down into the right atrium?
where does the L coronary artery come from?
ascending aorta
which vessels does the coronary sinus recieve?
middle, great, and oblique cardiac veins

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
