By Matt Hanley Digestive Processes GI tract Small Intestine Large Intestine Absorption GI Tract Mixes food with gastric acid Digests proteins HCL acid kills pathogens Mucus protects inner lining. By Erin and Courtney . . Evolution. Two types of digestion. Intracellular: Break down of macromolecules takes place within the cell.. Extracellular: Break down of macromolecules takes place outside of the cell. By Hannah, Madi, and Faith. What is the digestive system. It breaks down food into smaller substances. The mouth. Chemical digestion. Mechanical digestion. Taste buds. The epiglottis. Chemical digestion. Presented by: Milagro Chavez. Municipal solid waste (MSW).  Waste type . consisting of everyday items discarded by the public.. Food waste (FW). . Garbage: food that is discarded. Methane potential (MP). 2.

Carbohydrates are digested by salivary and pancreatic enzymes (. α-amylases. ) and by numerous . oligosaccharidases.  of the small intestine wall. The following table shows the enzymes that operate on starch.

Introduction. Factors responsible for . mechanical. and . chemical. . processes.. This occurs in the Alimentary Canal…. Alimentary canal . – long muscular tube that runs from the mouth to the . anus. . Peristalsis . – muscular movement of food. BIOMEDICAL IMPORTANCE. Besides water, the diet must provide metabolic fuels (mainly carbohydrates and lipids), protein (for growth and turnover of tissue proteins), fiber (for roughage), minerals (elements with specific metabolic functions), and vitamins and essential fatty acids (organic compounds needed in small amounts for essential metabolic and physiologic functions). . The digestive processes gradually break down the foods eaten until they are in a form suitable for absorption.. For example, meat, even when cooked, is chemically too complex to be absorbed from the alimentary canal.. BASIC FOODS. Carbohydrates, proteins and fats. Cannot be absorbed in native form. Require to be digested to absorbable form. CARBOHYDRATES IN FEED. Mostly Polysaccharides. Some disaccharides also. Di and poly .
