Secretion of digestive enzymes and other substances liquefies, adjusts the pH of, and chemically breaks down the food. Mechanical digestion is the process of physically breaking down food into smaller pieces. This process begins with the chewing of food and continues with the muscular churning of the stomach.

Even foods that are small enough to swallow without chewing should be chewed. Mastication prepares your food for Salivary functions in mastication, taste and textural perception, swallowing and initial digestion.

The human digestive system is responsible for food ingestion and digestion as well as the absorption of digested food molecules and the elimination of undigested molecules. It consists of a long tube called the gastrointestinal tract or GI tract (alimentary canal) and several accessory organs. The digestive system is the organ system that includes the gastrointestinal tract (GI tract) and its accessory organs. The digestive system processes food into molecules that can be absorbed and utilized by the cells of the body.

Liver Digestion is separated into four steps: Ingestion: placing food into the mouth (entry of food in the digestive system), Mechanical and chemical breakdown: mastication and the mixing of the resulting bolus with water, acids, bile and enzymes Absorption: of nutrients from the digestive system to The process of digestion begins in the mouth, but as previously mentioned, your salivary glands are gearing up long before food enters the mouth. Chewing (which is also known as mastication) breaks the food down into smaller pieces so that our digestive system can process the food more quickly. E) lever. B) large intestine.
