Everything begins in the mouth, where saliva is combined with mechanical food processing by the teeth. The amylase enzyme, which is present in saliva, starts to break down carbs, particularly starch. The food enters the esophagus after being chewed and combined with saliva in our mouths. Through peristaltic motions, the esophagus conveys food to the stomach. Pepsin and hydrochloric acid are secreted in the stomach, where they break down proteins in meals and produce an acidic environment that aids in digestion. The duodenum, the first segment of the small intestine, receives the food after it has been digested in the stomach. Bile and the pancreas are secreted here. Bile aids in the breakdown of proteins, lipids, and carbohydrates by the pancreas' enzymes.
