3 (tunica intima, tunica medi...
oxygenated - Answers the abdominal aorta carries _____________ blood to organs throughout the body
and plays a role in homeostasis.
superior-to-inferior - Answers Aorta is a retroperitoneal structure coursing in a
___________________________________ direction on the left side of the spine.
left ventricular, candy cane-shaped - Answers originates from the heart at the _____________ outflow
tract and follows a ____________________ loop into the thoracic cavity.
diaphragm, posterosuperior, iliac arteries - Answers after the aorta passes posteriorly to the
_____________ at the aorta hiatus on the ______________________ portion of the diaphragm, it is
termed the abdominal aorta.
The aorta continuous to course inferiorly and ends at its bifurcation into the ___________________.
internal, external - Answers iliac arteries bifurcate into ___________ and _____________ iliac arteries.
aortic branches - Answers 1-celiac artery (axis o trunk)
2-SMA (superior mesenteric artery)
3-renal arteries
4-gonadal arteries (GA)
5-IMA (inferior mesenteric artery)
celiac artery (axis o trunk) - Answers originates at the level of the pancrease and branches to common
hepatic splenic and left gastric arteries
, common hepatic artery - Answers courses laterally from CA to pts R side and bifurcates into **proper
hepatic arter and gastroduodenal (GDA) artery
left gastric artery (LGA) - Answers **courses superiorly and to the left
splenic artery (SA) - Answers courses laterally towards the pts left side
superior mesenteric artery (SMA) - Answers branches anterior-inferior from aorta w/in cm of celiac axis
and gives off branches which feed small intestine, portion of colon,pancreatic head and duodenal area
renal arteries (RA) - Answers R and L RA originate distal to the SMA and extend laterally to feed kidneys
gonadal arteries (GA) - Answers originate from anterior of the aorta and course inferiorly. R and L GA

pulsations. walls=less flexible then veins=very collapsible
celiac axis (CHA & SA) - Answers most easily seen in transverse plane slightly superior to pancreas (looks
like a seagull)
SMA - Answers identified in the longitudinal plane just distal to celiac axis
RAs - Answers best demo in transverse plane and appear as small-diameter curvilinear vessels branching
laterally from aorta. R RA seen in longitudinal plane coursing posteriorly to inferior vena cava.
common iliac arteries - Answers seen at level of umbilicus, best demo in transverse plane and then can
be evaluated longitudinally

doppler ultrasound - Answers stenosis of aortic brances is readily detected w?
bowel ischemia - Answers stenosis is often the causative factor in other disease states such as
_______________ resulting from SMA stenosis.
inferior vena cava (IVC) - Answers second great vessel of the abdomen
-size varies w/respiration and valsalva maneuver; considered dilated if diameter exceeds 3.7 cm
same, smaller - Answers compared w/the walls of the artery, veins have the _____ number of layers, the
tunica media is ______ and the composite wall is more flexible (low pressure system)
.deoxygenated - Answers primary function of the IVC is returning ____________ blood to the heart
