Chyme results from the mechanical and chemical breakdown of a bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes.
32.
Depending on the quantity and contents of the meal, the stomach will digest the food into chyme in anywhere between 40 minutes to a few hours.
33.
The men knew that the pancreas produces digestive juices in response to increased acidity in the duodenum and jejunum, because of the arrival of chyme there.
34.
:I just wanted to chyme in that there are certain plastics that contain helium well and the helium won't leak for a long time.
35.
The duodenum also produces the hormone secretin to stimulate the pancreatic secretion of large amounts of sodium bicarbonate, which then raises pH of the chyme to 7.
36.
Throughout the lining of the small intestine there are numerous brush border enzymes whose function is to further break down the chyme released from the stomach into absorbable particles.
37.
Segmentation contractions act to mix and move the chyme more slowly in the small intestine allowing more time for absorption ( and these continue in the large intestine ).
38.
Layers of circular and longitudinal smooth muscle enable the chyme ( partly digested food and water ) to be pushed along the ileum by waves of muscle contractions called peristalsis.
39.
When cooked, the combination of heat and the enzyme rennet in the intestines coagulates the chyme and creates a sort of thick, creamy, cheese-like sauce.
40.
While peristalsis involves one-way motion in the caudal direction, segmentation contractions move chyme in both directions, which allows greater mixing with the secretions of the intestines.
