ABSORPTION OF FLUID AND ELECTROLYTES

Fluid delivery to the GI tract is 8–10 L/d, including 2 L/d ingested; most is absorbed in small bowel. Colonic absorption is normally 0.05–2 L/d, with capacity for 6 L/d if required. Intestinal water absorption passively follows active transport of Na+, Cl, glucose, and bile salts. Additional transport mechanisms include Cl/HCO3 exchange, Na+/H+ exchange, H+, K+, Cl, and HCO3 secretion, Na+-glucose cotransport, and active Na+ transport across the basolateral membrane by Na+,K+-ATPase.
