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: -Gastric juice is made up of water, electrolytes, hydrochloric acid, enzymes, mucus, and intrinsic factor. Hydrochloric acid is a strong acid secreted by the parietal cells, and it lowers your stomach’s pH to around 2.
Detailed explanation-3: -chyme, a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and intestine during digestion. In the stomach, digestive juices are formed by the gastric glands; these secretions include the enzyme pepsin, which breaks down proteins, and hydrochloric acid.
Detailed explanation-4: -Food and liquids are broken down into a thick, acidic, soupy mixture called chyme. Once chyme is formed, the pyloric sphincter relaxes. Then the stomach muscles tighten and relax to help move the chyme into the duodenum where digestion continues and many nutrients are absorbed (taken up).
