Explanation:
Digestion may be defined as the process of breakdown of large food particle into simpler substances with the help of digestive enzymes and juices.
The process of food breakdown starts from the mouth. The physical breakdown of food helps with the mastication of teeth. The salivary amylase breaks down carbohydrate into mouth. Food then passes down to the esophagus with the help of peristaltic movements. The food then enters in the stomach forms chyme with the help of mixing of food with gastric juice. Hydrochloric acid kills the harmful bacteria in the stomach. The food then passes into the small intestine ( duodenum, jejunum and ileum). The bile juice, pancreatic juice and various enzymes are present in the small intestine. The carbohydrates are breakdown into simple sugars, proteins into amino acid and fatty acid into simple fats. The maximum absorption and complete digestion occur in the small intestine. The excess material and waste product passes into the large intestine and excrete out from the body through rectum.
