  • What is the major site for nutrient absorption in the alimentary canal?
    It is the major site for nutrient absorption.
  • What makes the small intestine uniquely suited for nutrient absorption?
    The small intestine has a large surface area due to structures like microvilli, which maximize nutrient absorption.
  • What are the three sections of the small intestine?
    The three sections of the small intestine are the duodenum, jejunum, and ileum.
  • What is the primary function of the jejunum?
    The primary function of the jejunum is nutrient absorption.
  • How does the duodenum protect itself from the acidic chyme from the stomach?
    The duodenum releases an alkaline mucus to neutralize the acidic chyme.
  • What role do enterocytes play in the small intestine?
    Enterocytes are specialized for absorption and line the villi of the small intestine.
  • What is the function of goblet cells in the small intestine?
    Goblet cells secrete mucus to provide a protective lining in the small intestine.
  • What is the purpose of peristalsis in the small intestine?
    Peristalsis moves chyme through the small intestine by wave-like muscle contractions.
  • What is the function of Peyer's patches in the ileum?
    Peyer's patches protect against pathogens by housing lymphoid tissue in the ileum.
  • How do microvilli contribute to digestion in the small intestine?
    Microvilli increase surface area for absorption and contain brush border enzymes for digestion.
