So inside our stomach, not only do we have mechanical digestion taking place, but we also have chemical digestion. Basically, the enzymes break down our peptide, the polypeptides, into their amino acids as well as into smaller peptides. Now, inside the stomach, we have ultimately no absorption taking place. Certain substances such as alcohol and aspirin are absorbed by the stomach. But the food products are not absorbed in the stomach. The absorption of the food products, as we'll see in just a moment, takes place in the small intestine.
