Paracellular Pathways

Paracellular Pathways

Overview

• Major routes of ion movement.

Transport Mechanism

• Active transport of ions, monosaccharides, and amino acids creates osmotic pressure.

• Water and electrolytes are drawn across the intestinal wall.

Significance of Ion Transport

• Accounts for significant amounts of ion transport, especially sodium.

• Sodium is crucial for stimulating glucose absorption.

Absorption Mechanisms

• Glucose and amino acids are transported into the blood via sodium-dependent cotransport.

• Key for treating diarrhea.
