Inferior vena cava (IVC)

Small intestine /

duodenum

Note the branches of the superior mesenteric artery. The SMA begins to diverge off smaller arteries throughout the mesentery in order to deliver arterial blood to the mesenteric viscera. What organs are serviced by the superior mesenteric artery? Where does this arterial blood drain?

ID all 4 (actually 5) arteries that branch from the dorsal/abdominal/descending aorta that you can see in this image (other than the common iliac arteries).

What organs do they deliver arterial blood to?How do those respective organs return venous blood to the heart?

Despite clearly visualizing the abdominal vasculature, remember that these arteries and veins are retroperitoneal. Note the progression of images. In order to visualize these major arteries in a patient, you’d have to make an incision in the peritoneum.

Abdominal cavity

Abdominal cavity: bowel reflected cranially

Incised peritoneal membrane to visualize WHICH ARTERIES?

Right external iliac artery

“Right inguinal ligament” (where right external iliac artery transitions to right

femoral artery)

Right femoral artery

_______ _______

Nerve

Femoral artery

Femoral artery

Deep femoral artery

Mesentery

Mesentery

Notice how mesentric artery on the right is much smaller in diameter (NOT the superior mesenteric artery as it branches off the dorsal/descending/abdominal aorta) within the mesentery. Also note how the probe in the left image is retracting a region of the superior mesenteric vein that will eventually anastomize with the hepatic portal vein.
