Food is chewed in the month and the teeth break it down into small fragments, so that the digestive juices can deal with it easily. At the same time,the food is mixed with saliva, secreted by the salivary glands in the mouth. Our tongue assist in forming a round ball of food called a bolus.

Food is prevented from entering the windpipe by the epiglottis which closes over the windpipe whenever anything is swallowed. The gullet consist of a tube with an outer layer of muscle and an inner lining.The whole process from food entering the mouth to its entering stomach is known as ingestion

The stomach wall contains many small glands which secrete digestive juices.
