ANATOMY

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: -The lining of the stomach produces gastric juices that contain protein-digesting enzymes. Peristaltic movements of the stomach wall mix and churn the food with the gastric juices. This action further breaks up the food particles, forming a milky fluid known as chyme.

Detailed explanation-3: -In addition to the circular and longitudinal muscles, the stomach has diagonal muscles which make it possible for the stomach to twist and churn. This kneading effect actually breaks up food.

Detailed explanation-4: -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.
