Storyboard Text

  • You're in HBS, how does my body digest this bread?
  • The first step is using your teeth and tongue to mechanically digest your bread, then your salivatory glands use amylase to digest the starch in the bread. Turning the chewed food into a bolus.
  • Then what happens???
  • After a bolus if formed deglutition (Swallowing) occurs, the bolus glides through your pharynx (throat). Then, penstalis helps move bolus through your esophagus.
  • Where does it go from there?
  • From the esophagus, the bolus reaches your pyloric sphincter right before entering your stomach. However, before you even started eating, your stomach creates gasmic "juice" that helps digest bolus.
  • In the stomach, chemical and mechanical digestion occurs. HCl and Pepsin digest bolus, and sloshing and churning continue mechanical digestion. Then, chyme is formed moving toward the pyloric sphincter.
  • Chyme then reaches the small intestine. Bile and pancreatic enzymes add to chyme in duodenum. Nutrient absorption takes place, and is then sent into blood stream. Paristalis moves non-needed materials and water through small intestines.
  • Chyme reaches the large intestine, and water absorption takes place. Paristalis moves non-digestive materials through and turns it into feces. The rectum receives the non-digestable materials and expands for storage.
  • The internal anal sphincter sends signals to brain. Then the brain tell the body to find a bathroom. The feces then reaches the anus, and moves to the external anal sphincter, and defecation occurs.
