where does the chyme go when it leaves the stomach?
into the small intestine
once processed and digested by the stomach, the milky chyme is squeezed through the pyloric sphincter into the small intestine. once past the stomach, a typical peristaltic wave only lasts for a few seconds, travelling at only a few centimeters per second. its primary purpose is to mix the chyme in the intestine rather than to move it forward in the intestine. through this process of mixing and continued digestion and absorption of nutrients, the chyme gradually works its way through the small intestine to the large intestine.
peristalsis
in the human digestive system, a bolus (a small rounded mass of chewed up food) enters the stomach through the oesophagus via the lower oesophageal sphincter. the stomach releases proteases (protein-digesting enzymes such as pepsin) and hydrochloric acid, which kills or inhibits bacteria and provides the acidic ph of 2 for the proteases to work. food is churned by the stomach through muscular contractions of the wall called peristalsis – reducing the volume of the bolus, before looping around the fundus and the body of stomach as the boluses are converted into chyme (partially digested food). chyme slowly passes through the pyloric sphincter and into the duodenum of the small intestine, where the extraction of nutrients begins. depending on the quantity and contents of the meal, the stomach will digest the food into chyme within anywhere between forty minutes and a few hours . the average human stomach can comfortably hold about a litre of food.
