This MCQ quiz assesses knowledge on gastrointestinal processes, focusing on aspects like pancreatic function, sugar absorption, reflex responses to eating, enzyme activities, and water reabsorption. It is designed for medical students and professionals.
Absorption would be increased by adding equimolar amounts of glucose to the lumina! solution
Absorption would be increased by adding ouabain (an inhibitor of the Na,K-ATPase) to the bath
Absorption would be increase addition of amiloride (an inhibitor of ENaC) to the luminal solution
Absorption would be decreases by adding equimolar amounts of fructose to the luminal solution
Absorption would be decreased by replacing 02 in the bathing solution with N2.

The center of classic liver lobule is occupied by portal triad
Portal lobule is a triangular-shaped structure with central veins at the periphery.
Liver acinus is a triangular-shaped structure.
Zone one in liver acinus will be the first zone to undergo necrosis under hypoperfusion and hypoxia.
Cells in zone three of liver acinus are also called perilobular cells.
