Lab #12: Digestive Physiology

Lab #12: Digestive Physiology p.1. Lab #12: Digestive Physiology. Background. In order for the nutrients in food to be absorbed, they must first be broken down into particles that are small enough to be transported through carrier proteins into the epithelial cells that form the mucosal lining of the digestive tract. This process  ...


The Digestive System & Enzymes Mandatory Experiment

Digestion is the breakdown of large, insoluble food molecules into small soluble food molecules. There are two types of digestion: Physical digestion – food broken down by teeth and churning action of muscles in the digestive system. Chemical digestion – food is broken down by enzymes. Enzymes are biological catalysts.
