inferior mesenteric, gastric, and cystic veins. The hepatic portal vein receives de-
oxygenated blood from the inferior and superior mesenteric vein and splenic vein
and delivers nutrients that have been absorbed from the intestinal system

intestines. This pulls water by osmosis into the intestinal lumen and results in large
volume diarrhea.This is how mag citrate, lactulose and miralax work. Causesinclude:
excessive ingestion of nonabsorbable sugars, tube feedings, dumping syndrome,

matory bowel disease, cancer, diverticula or hemorrhoids. Hematochezia, or the
presence of bright red blood in the stools, suggest what kind of bleed

stomach or duodenum resulting in exposure of the tissue to gastric acid. Risk factors
include smoking, advanced age, NSAID use, ETOH, chronic disease, acutepancreatitis,
COPD, obesity, socioeconomic status, gastrinoma, and infection withHelicobacter
pylori. S&S: Epigastric pain is worse with eating, melena or hemateme-sis
