GENERAL HISTOLOGY

Detailed explanation-1: -Chemical digestion is facilitated by the churning action of the stomach. Contraction and relaxation of smooth muscles mixes the stomach contents about every 20 minutes. The partially-digested food and gastric juice mixture is called chyme. Chyme passes from the stomach to the small intestine.

Detailed explanation-2: -Once your food is broken down, your stomach stores it in an acidic liquid called chyme. Chyme is gradually released into the small intestine.

Detailed explanation-3: -Chyme results from the mechanical and chemical breakdown of a bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes. Chyme slowly passes through the pyloric sphincter and into the duodenum, where the extraction of nutrients begins.

Detailed explanation-4: -Muscular contractions of the stomach walls help to mix food and digestive substances together in forming chyme. As particles of food become small enough, they are passed at regular intervals into the small intestine. Once in the intestine, more enzymes are added and mixing continues.

Detailed explanation-5: -Mechanical digestion occurs as layers of muscle in the stomach lining contract to produce a mixing and churning motion. Chemical digestion is carried out by stomach juices that contain enzymes and hydrochloric acid. When the food has been turned into liquid form, it moves onto the small intestine.
