WebbThe first step in this process is ingestion. Ingestion is the process of taking in food through the mouth. In vertebrates, the teeth, saliva, and tongue play important roles in mastication (preparing the food into bolus). While the food is being mechanically broken down, the enzymes in saliva begin to chemically process the food as well.

"WebbKey Points. Food is ingested through the mouth and broken down through mastication (chewing). Food must be chewed in order to be swallowed and broken down by digestive enzymes. While food is being chewed, saliva chemically processes the food to aid in swallowing. Medications and harmful or inedible substances may be ingested as well. " - Propulsion biology digestive system

WebbAbsorption. Although the small intestine is only 3 to 4 cm in diameter and approximately 7 metres in length, it has been estimated that its total absorptive surface area is approximately 4,500 square metres (5,400 square yards). This enormous absorptive surface is provided by the unique structure of the mucosa, which is arranged in … WebbThe digestive system is essentially a very long tube that stretches from the back of the mouth to the anus. When we eat, food passes down the oesophagus to the stomach, squeezed by regular contractions – this is called peristalsis. When the food reaches the stomach, it is broken down into a mushy liquid called chyme by acids and enzymes.
