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: -In the large intestine, bacteria break down any proteins and starches in chyme that were not digested fully in the small intestine. When all of the nutrients have been absorbed from chyme, the remaining waste material changes into semisolids that are called feces.

Detailed explanation-3: -Once the chyme is well mixed, waves of muscle contractions propel it through a valve called the pylorus and into the upper section of your small intestine (duodenum). The pylorus might release about an eighth of an ounce (about 4 milliliters) of chyme at a time.

Detailed explanation-4: -Chyme is then squirted down into the small intestine, where digestion of food continues so the body can absorb the nutrients into the bloodstream.
