Detailed explanation-1: -The second stage of digestion begins in the stomach with the gastric phase. Here the food is further broken down by mixing with gastric acid until it passes into the duodenum, the first part of the small intestine.

Detailed explanation-2: -In the mouth, where the second step of digestion occurs, the mechanical and chemical breakdown of food begins. The chemical breakdown of food involves enzymes, which break apart the components in food. In the mouth, the enzyme amylase is secreted to begin breaking down complex carbohydrates.

Detailed explanation-3: -Figure 2: The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.

Detailed explanation-4: -The stomach slowly empties its contents, called chyme, into your small intestine. Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion.

Detailed explanation-5: -When you’re ready to swallow, the tongue pushes a tiny bit of mushed-up food called a bolus (say: BO-luss) toward the back of your throat and into the opening of your esophagus, the second part of the digestive tract.
