Now, although our stomach does actually absorb certain types of molecules such as, for example, caffeine as we mentioned earlier aspirin, as well as alcohol it acts mostly in digestion. It doesn't actually absorb the nutrients in the stomach. Where the nutrients are absorbed are in the small intestine as we'll see in the next lecture. Now, the cells of our stomach basically work together to secrete this gastric juice that consists of many different things. It consists of hydrochloric acid, it consists of these enzymes as well as these other molecules that basically help stimulate the cells to release our gastric juice. And what the gastric juice does is it breaks down our food into smaller molecules and together the mixing of the gastric acid and the food turns the food into a fluid like substance we call chain.
