Passing on the partly digested food leaves the stomach, having an acid reaction and called chyme. As it enters the intestine, this chyme is attacked by the bile, which serves to neutralize the acid reaction, and further to aid in digesting the fats and oils. Then the pancreatic juice renders the mass fit for the blood to assimilate, and finishes the digestion of the fats and oils...
