mechanically broken down. An enzyme named salivary amylase breaks starch into chunks of glucose called dextrins and maltose(disaccharide maltose). Once the food reaches the stomach‚ the acid in the stomach inactivates all salivary amylase. Carbohydrate digestion is not conducted the stomach for this reason. Before the food approaches the small intestine‚ the pancreas secretes pancreatic amylase. The pancreatic amylase digests starch into maltose. The enzymes maltase‚ sucrose‚ and lactase mucosal cells

qualities. The E stands for European which means it is approved by Europe. Digestion and Absorption: - Digestion is the breakdown of food into smaller particles or individual nutrients. It is accomplished through six basic processes‚ with the help of several body fluids—particularly digestive juices that are made up of compounds such as saliva‚ mucus‚ enzymes ‚ hydrochloric acid‚ bicarbonate‚ and bile . The six processes of digestion involve: (1) the movement of food and liquids; (2) the lubrication of

for cell metabolism‚ including the maintenance and repair of cells and growth. In humans‚ digestion and absorption occur in the alimentary canal or gut. As the gut wall is continuous with the outside surface of the body‚ the food in the gut is considered to be outside of the body‚ the gut is specialised into different regions‚ each designed to carry out a different role in the overall processes of digestion and absorption. The human gut is a coiled‚ muscular tube extending from the mouth to the

These processes are motility‚ secretion‚ digestion‚ absorption‚ and excretion. Motility is the mechanical processing and movement of food taken into the body. Chewing breaks food into smaller pieces‚ and two types of movement mix the contents of the lumen and propel it forward. The lumen is the inside lining of the GI tract. Secretion is the fluid‚ digestive enzymes‚ acid‚ alkali‚ bile‚ and mucus that are secreted into the GI tract at various places. Digestion is where the contents of the lumen are
