"The digestive juices in your stomach break down the food into a thick liquid called chyme which then is passed into the small intestine."
Chyme is the result of the partial chemical and mechanical digestion that occurs over the bolus in the stomach. It is a semi-fluid mass of partially digested food, digestive enzymes, water, and HCl (so it has a very low pH). By stomach movements, the chyme is pushed against the pyloric valve and passes in very small quantities to the duodenum, which is the beginning of the small intestine.
