GENERAL HISTOLOGY

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. 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-3: -Waves of muscle contractions called peristalsis (pronounced: per-uh-STALL-sus) force food down through the esophagus to the stomach. A person normally isn’t aware of the movements of the esophagus, stomach, and intestine that take place as food passes through the digestive tract.

Detailed explanation-4: -The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.

Detailed explanation-5: -It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach. There, the food is churned into a liquid mixture called chyme that moves into the small intestine where peristalsis continues.
