mechanical process of digestion

Chewing is especially important when eating. Salivary glands release saliva during mastication to soften the meal into a bolus (a semi-solid lump). The bolus is then pushed by wave-like muscular contractions called peristalsis that moves the food to the stomach. The main purpose of mechanical digestion is to break down the large chunks of food that can't be consumed in a single bite or swallow. . The small intestine is divided into three parts, known as the duodenum, the jejunum, and the ileum. The digestive system is made of different tract as seen in figure 1.2.
