L and R gastro-omental a.
What gives off the L gastro-omental a?
What gives of the R gastro-omental a?
Where do the L and R gastric veins drain into after draining the lesser curvature of the stomach?
directly into the hepatic portal v.
Where does the L gastro-omental v. drain into?

Peptic ulcers lead to a risk of wall perforation and damage to what nearby structures?
Pancreas and splenic a.
protrusion of portion of the stomach superiorly through esophageal hiatus
At what level of ribs is the spleen?
What is the role of the spleen?
lymphatic organ, and also recycles heme from RBCs
What are the metabolic functions of the liver?
stores glycogen, and produces bile

What lobe of the liver is inferior and between the round ligament and the gallbladder?
What lobe of the liver is superior and between the ligament venosum and the IVC?
in adults this represents remnants of fetal shunt & links ligament teres (round ligament of the liver) with IVC

The hepatic portal v is primarily a merger of what 2 veins?
splenic and superior mesenteric v.
The hepatic portal v is formed by what major unpaired veins from the foregut?
splenic v. and gastric vv.
The hepatic portal v is formed by what major vein from the midgut?
The hepatic portal v is formed by what major vein from the hindgut?
What are the veins of the collateral pathways that will reverse their flow from the hepatic portal v. to the IVC, if flow to the liver is compromised?
esophageal vv, paraumbilical vv. colic vv. and rectal vv.
Blockage of BF into the liver increases pressure upstream, forcing blood into portal-systemic anastomoses, causing what?
portal hypertension leads to dangerous pressure in small vessels, what is this common side effect?
Increased BP in visceral capillary beds = edema, leads to fluid builds up in peritoneal cavity, can lead to peritonitis, and renal failure, this is known as...
Blood processed by the liver collects in ...
3 short hepatic veins and drains into IVC
