In
digestion, a bolus () is a ball-like mixture of food and
saliva that forms in the mouth during the process of
chewing (which is largely an adaptation for
plant-eating mammals). It has the same color as the food being eaten, and the saliva gives it an
alkaline pH.
Under normal circumstances, the bolus is
swallowed, and travels down the
esophagus to the
stomach for digestion.
