Some digestion happens in the stomach, but that's only part of the process. It actually starts in the mouth where food is chewed and lubricated by saliva, which also adds amylase, an enzyme that starts the digestion process whilst you chew. In the stomach, food is churned in an acid bath, before being squirted in teaspoon-size portions into the small intestine. It’s here that the acidic food solution (called 'chyme') is neutralised, before digestive enzymes from the pancreas and bile from the gallbladder are added, helping you fully digest your meal and then absorb it into the body. Microbes in the colon (large intestine) then deal with what’s left, before the waste passes through and out of the body.
