Sindirimin

Sindirimin is the Turkish term for digestion, the set of physiological processes by which food is broken down into smaller molecules that can be absorbed and used by the body. In humans, sindirimin involves mechanical and chemical steps that begin in the mouth and continue through the gastrointestinal tract.

Mechanical digestion includes chewing and stomach churning that increase surface area and facilitate chemical breakdown. Chemical digestion uses enzymes, acids, and bile. Saliva contains amylase to begin carbohydrate digestion. The stomach secretes hydrochloric acid and pepsin to start protein digestion, while gastric motility forms a semi-liquid substance called chyme.

The small intestine is the primary site of digestion and absorption. Pancreatic enzymes (amylase, lipase, proteases) and bile acids mix with chyme to emulsify fats and further digest nutrients. Brush-border enzymes on the intestinal lining complete the digestion of disaccharides and peptides. Nutrients are absorbed mainly in the small intestine via the mucosal surface; fats are absorbed into the lymphatic system, while other nutrients enter the bloodstream.

The large intestine absorbs water and electrolytes and hosts microbial fermentation that yields short-chain fatty acids and other metabolites, contributing to gut health. It also forms and stores feces until elimination.

Regulation of sindirimin involves the enteric nervous system and hormones such as gastrin, secretin, and cholecystokinin, which coordinate secretion, motility, and timing of gastric emptying and intestinal digestion. Disturbances in sindirimin can lead to malabsorption, dyspepsia, gastroesophageal reflux, or inflammatory bowel conditions.
