Digestive System Lab Stations

What you will do today… Observe the length and the arrangement of the digestive tract from start to finish Investigate the role of villi and microvilli in absorbing nutrients into the bloodstream Contrast mechanical and chemical digestion Reenact the role of each digestive structure as food passes down the length of the digestive tract

What is digestion? Mechanical Digestion: the breakdown of food into smaller pieces Chemical Digestion: the breakdown of molecules into smaller molecules using enzymes
