Digestive System, Part 3: Crash Course Anatomy & Physiology #35

Nachos are great...if you are among the lucky ones whose bodies can digest them. When digestion goes according to plan, the small intestine performs most of your chemical digestion in the duodenum, while accessory organs including the liver, gallbladder, and pancreas contribute enzymes that all but finish the job. Then your large intestine, which is actually shorter than the small intestine, tries to extract the last bit of nutrition, including the occasional attempt to turn nachos into energy, which for most humans, ends in gassy failure.

Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!
