On entering the stomach, food is mixed with gastric juices and churned by contractions of muscles in the stomach wall. Food usually stays in the stomach for about four hours. By that time, it has become a semi-liquid (called chyme) that can be released in spurts into the duodenum, the first part of the small intestine.
INSIDE THE STOMACH
When food enters the stomach, glands in its lining release an enzyme, pepsin. This begins to break down protein in food. The lining also produces hydrochloric acid, which maintains the acid environment needed for pepsin to work and kills any bacteria present.
INTESTINES
The intestines form a continuous tube that is about 8 m (26 ft) long in adults. Food is pushed along this tube by contractions of muscles in the intestinal walls. In the small intestine, muscle contractions mix chyme with enzymes produced by the pancreas and intestinal lining. It is here that nutrients are absorbed into the bloodstream. In the large intestine, water is absorbed from the digestive waste, and the remaining waste is formed into stools.
VILLI OF SMALL INTESTINE
The lining of the small intestine has a huge surface area due to the folds in its lining as well as villi, tiny fingerlike structures that project from the lining. Once digested, nutrients are absorbed into tiny blood vessels within the villi. They are then carried in the blood to the liver for processing. Food can remain in the small intestine for up to five hours.
INTESTINAL BACTERIA
The intestines are home to more than 500 species of bacteria, which they need to function effectively. Some of these bacteria are thought to protect the intestines from disease. Certain bacteria in the large intestine make vitamin K, which the body needs for blood clotting

The food will be created in liquid form and it will mix with blood or it will be blood.
