Prompt
A Primary data viva — identify the three splanchnic arteries by territory; explain first-pass metabolism; describe gut ischaemia, barrier failure and bacterial translocation in shock.
Stimulus
A schematic diagram shows the gut tube with the celiac, superior mesenteric and inferior mesenteric arteries, and the portal vein draining to the liver. Identify each artery and its territory, explain the portal first-pass arrangement, and state what happens to the gut in shock.
