Storyboard Text

  • Betty begins to eat her apple. The apple is about to embark on a two day adventure through her digestive system. Digestion starts in the mouth and immediately she chews her food with her teeth while simultaneously producing saliva which contains the enzyme salivary amylase which help break up starch and lubricate her food. The bite of apple is now called a bolus and moves from her mouth into her pharynx where it is swallowed. The bolus enters the esophagus and muscular contractions move it down the esophagus into the stomach.
  • Once the bolus arrives in the stomach (dark blue) it is broken down by mechanical and chemical digestion. The bolus mixes with stomach gastric juices and turns into chyme. From here the chyme will be transported to the small intestine.
  • The first part of the small intestine (purple) is called the duodenum and here the digestive enzymes from the liver and pancreas enter to make the chyme smaller so its nutrients and energy can be absorbed into your blood stream.
  • Ville in the small intestine (purple) gather the nutrients it needs. The pancreas (grey) produces enzymes that digest carbohydrates, fats, and proteins. The liver (blue) produces bile that breaks down fat and the excess bile is stored in the gallbladder (green)
  • Once the chyme leaves the small intestine it enters the large intestine (light blue)All nutrients were absorbed in the small intestine so now the large intestine takes care of the waste like fiber, water, dead cells, and salts. The large intestine stores indigestible material until it is eliminated as faces.
  • The colon pushes the left over waste (stool) into your rectum and then finally the stool is released from the anus. The process of digestion is now complete!
