It furthermore emulsifies the fat or divides it into extremely fine drops. The food passes now into a long coiled pipe the small intestine. This secretes the intestinal juice which further assists the pancreatic juice.
This will gradually separate upon standing, the pancreatic extract settling in the water at the bottom. When shaken it will again form an emulsion. Experiment 61. To show the action of pancreatic juice on starch. Put two tablespoonfuls of smooth starch paste into a goblet, and while still so warm as just to be borne by the mouth, stir into it two grains of the extract of pancreas.
I would one day have all the signs of pancreatic disease; perhaps the next I would display unmistakable evidences of ascending myelitis; next, my liver would be the storm center, and so on. My shifting of symptoms was gauged by the lecturers to whom I listened. At my room one evening I was walking the floor wrapped in deepest gloom.
This motion continues until the contents of the stomach are converted into chyme, and conveyed into the first intestine, where they undergo another important change. CHYLIFICATION. As fast as chyme is formed, it is expelled by the contractile power of the stomach into the duodenum, or first intestine. It there meets with the bile from the liver, and with the pancreatic juice.
But if by a greater stimulus the motions of the stomach are inverted still more violently or more permanently, the duodenum has its peristaltic motions inverted at the same time by their association with those of the stomach; and the bile and pancreatic juice, which it contains, are by the inverted motions brought up into the stomach, and discharged along with its contents; while a greater quantity of bile and pancreatic juice is poured into this intestine; as the glands, that secrete them, are by their association with the motions of the intestine excited into stronger action than usual.
It is continuous with the outside skin of the body, as may be seen at the lips. Pan'cre as. The gland that secretes the pancreatic juice; located in the abdominal cavity near the stomach. Pan cre at'ic juice. An alkaline digestive juice poured by the pancreas into the small intestine; especially valuable in the digestion of starches, fats, and proteins. Per i to ne'um.
Such waste materials as the liver cannot burn down so that the kidneys and skin can handle them, it pours out through its duct into the intestine as the bile. The bile is a yellowish-brown fluid, which assists the pancreatic juice in the digestion of the food, and helps to dissolve the fats eaten, but is chiefly a waste product.
Other digestive secretions from the pancreatic gland and the liver are poured into the small intestine near its origin. These digestive juices act on the proteids, sugars, starches and fats, changing them into substances that are capable of being absorbed.
As the food is pushed along over the common opening of the bile and pancreatic ducts, a great quantity of bile from this reservoir, the gall bladder, is poured into the intestines. These two digestive fluids are now mixed with the chyme, and act upon it in the remarkable manner just described.
Therefore all the starches which we eat bread, biscuit, potato, etc. have to be acted upon by the ferments of our saliva and our pancreatic juice, and turned into sugar, called glucose, which can be easily poured into the blood and carried wherever it is needed, all over the body.
