The only chyme molecule that is absorbed in significant amounts by the stomach is water.
Answer the following statement true (T) or false (F)
True
Chyme is a solution that contains water, salts, molecular fragments of proteins, nucleic acids, polysaccharides, droplets of fat, and various other small molecules. Virtually none of these molecules, except water, can cross the epithelium of the stomach wall; therefore, little or no absorption of organic nutrients occurs in the stomach.
