3. Duodenum -as most food is absorbed in duodenum so resection of this will decrease absorption and promote weight loss.
4. Gastroentric Reflex - it regulate acid secretion NOT motility.
5. Fructose - as sucrose is diasaccharide made of 2 monosacharide Glucose and fructose.
6. GIP, VIP, CCK and Secretin.
