Detailed explanation-1: -The stomach muscles churn and mix the food with digestive juices that have acids and enzymes. These juices help break up food into much smaller pieces. By the time food is ready to leave the stomach, it has been turned into a thick liquid called chyme (kime).

Detailed explanation-2: -Stomach: An organ with strong muscular walls, the stomach holds the food and mixes it with acid and enzymes that continue to break the food down into a liquid or paste. Small Intestine (Small Bowel): Almost 20 feet long, the small intestine is the workhorse of the digestive system.

Detailed explanation-3: -Stomach. The stomach wall produces gastric juice (hydrochloric acid and enzymes) that digests proteins. The stomach acts like a concrete mixer, churning and mixing food with gastric juice to form chyme-a thick, soupy liquid.

Detailed explanation-4: -Once food is swallowed, it passes through the esophagus into the stomach, the pink organ shown here above the yellow pancreas. A large, muscular chamber, the stomach produces digestive juices like pepsin, lipase, and hydrochloric acid, which digest and dissolve stomach contents.

Detailed explanation-5: -What is chyme and how does the stomach mix this material? Chyme is a thick semi-fluid of partially digested foods do digestive secretions that forms in the stomach and intestine during digestion. Muscle contractions of the stomach walls help mix food and digestive substances together, forming chyme.
