31
What is the Marginal Artery (of Drummond)
Collection of anastomoses of the branches of the mesenteric arteries that runs the entire length of the inner border of colon
32

provide collateral circulation between middle colic artery (SMA) and left colic artery (IMA)
33

IMA
34
Function of Portal Vein?
transports deoxygenated, nutrient-rich blood from GI tract to liver where it is processed and dumped into IVC
35
What 3 veins come together to form portal vein?
Splenic vein Superior Mesenteric Vein Inferior Mesenteric Vein
36
Venous return of foregut, midgut, hindgut?
Splenic vein-foregut SMV-midgut IMV-hindgut
37
What is characteristic of the portal vein that differs from other circulation?
NO VALVES
38
How does blood flow in the portal circulation?
Blood from RIGHT side (SMV) preferentially flows to RIGHT SIDE OF LIVER Blood from LEFT side (IMV and SPLENIC v) flows to LEFT SIDE OF LIVER
