Question

Quizplus · Accepted Answer

Short-chain fatty acids such as acetate, propionate, and butyrate have been shown to increase colonic blood flow by acting as vasodilators and improving mucosal integrity. They also enhance splanchnic blood flow by promoting the release of glucagon-like peptide 1 (GLP-1), which stimulates intestinal blood flow and improves nutrient absorption.
