Process of Digestion© Copyright NewPath Learning. All Rights Reserved. 94-4945Visit www.newpathlearning.com for Online Learning Resources.Mechanical DigestionFood is broken apart physically to make it easier for chemical digestion to occur. This process starts with chewing our food and mixing it with saliva and is followed by a physical churning that takes place in the stomach.pancreasstomachintestinessalivary glands amylase amylase pepsin lipase protease maltase lactase peptidaseChemical Digestion Food is chemically digested by enzymes that break chemical bonds between food molecules. This process makes food molecules less complex and easier to absorb. Chemical digestion of carbohydrates begins in the mouth with the release of the enzyme amylase within the saliva. Chemical digestion of proteins starts in the stomach. The majority of chemical digestion, however, occurs in the small intestine.Pancreatic EnzymesThe greatest number and variety of digestive enzymes are released by the pancreas. Pancreatic enzymes digest carbohydrates, proteins and lipids in our foods. Carbohydrates are broken down to simple sugars, and proteins are broken down to amino acids. Fats are broken down to triglycerides and fatty acids. These end products of digestion can then be absorbed into the body to sustain life.amylase lipaseproteasePancreaticEnzymeFood particleSimplest form(molecules)carbohydratesproteinsfatssimple sugarsamino acidstriglyceridesfatty acidsAbsorption of NutrientsEnd products of digestion and many other molecules, including water, are absorbed through the lining of our digestive tract into the bloodstream. Most of this absorption happens within the small intestine. These nutrients are transported to vital organs in support of body functions and other chemical reactions.smallintestinesnutrientsnutrients absorbedthrough intestinal wallprocessedfoodpancreasstomachsmall intestine(duodenum)pancreaticenzymessugarscarbohydrateenzymeFood is broken apart physically to make it easier for chemical digestion to occur.
