Absorption and digestion of food in the pancreas • Pancreas secretes digestive juices • They are the maltase, lipase and protease enzyme • Enzyme break down the food into smaller particles • Thus the diffusion of the food particles into the bloodstream through the villi is made efficient
Enzymes secreted by the pancreas • Amylase changes starch into maltose • Trypsin changes protein into polypeptides • Lipase changes fats into fatty acids and glycerols
What happens if the pancreas malfunctions • Lack of insulin resulting in digestive problem • Pancreatic diseases, e.g.pancreatitis,diabetes mellitus, exocrine panreatic insufficiency.
