what do the azygous and hemiazygos flow into?

which veins flow into the heart?
inferior and superior vena cava, coronary veins
thickened outer layer of the heart
pericardium
which artery is considered the widowmaker?
LAD
which arteries leave the heart?
-pulmonic artery
- aorta

pectinate muscle located in the…
atrium
in what vessel is a DVT most likely
popliteal vein
what valves are closed during systole
mitral and tricuspid
What is the purpose of the coronary sinus?
drains into R atrium at coronary sinus orifice between inferior vena cava and tricuspid valve
when the myocardium is relaxed, blood is supplied through…
coronary arteries
where does the coronary sinus drain?
drains into R atrium at coronary sinus orifice between IVC and tricuspid valve
what branches off the superior vena cava
r cephalic, L cephalic, azygous
formaen ovale becomes….
fossa ovale
ductus arteriosum becomes….location?
becomes ligamentum arteriosum from pulmonary artery to aorta
branches of the aorta
right brachiocephalic
left common carotid
left subclavian
spinal level of the trachea
T4
3 places the aorta attaches to make it stable

-Ligamentum arteriosum
-Behind median arcuate ligament of the diaphragm
esophageal, pulmonary, and cardiac plexus all arise from
vagus n
azygous vein feeds into…
