Gastric emptying and intestinal absorption of fluid
age-related reduction
CLOT
In the present study, the difference in fluid balance response between young and older adult groups may be influenced mostly by gastric emptying rates. In older adults an age-related reduction in gastric acid secretion would potentially allow for a greater gastric emptying rate of milk by reducing casein clot formation (Huppertz and Chi Most of the water (ingested and emptied into the gastrointestinal tract) is reabsorbed in the small intestine, and remaining water in the colon. The small intestine is highly permeable promoting a rapid balance of the digestive content through the absorption of electrolytes and nutrients (Leiper
