Text Appearing Before Image:
DIGESTION AND ABSORPTION 305 chemical that would be visible under the X-ray. It was found that shortly after food reached the stomach a series of waves began which sent the food toward the pyloric end of the stomach. If the cat was feeling happy and well, these contractions continued regularly, but if the cat was cross or bad tempered, the movements would stop. This shows the importance of cheerfulness at meals. Other experiments showed that food which was churned into a soft mass was only permitted to leave the stomach when it became thoroughly permeated by the gastric juice. It is the acid in the partly digested food that causes the stomach valve to open and allow its contents to escape little by little into the small intestine. The partly digested food in the small intestine almost imme- diately comes in contact with fluids from two glands, the liver and pancreas. We shall first consider the function of the pancreas. Position and Structure of the Pancreas. - The most important digestive gland in the human body is the pancreas. The gland is a rather diffuse structure ; its duct empties by a common opening with the bile duct into the small intestine, a short distance below the pylorus. In internal structure, the pancreas resembles the salivary glands. Work done by the Pancreas. - - Starch paste added to artificial pancreatic fluid and kept at blood heat is soon changed to sugar. Protein, under the same conditions, is changed to a peptone.
