Study Notes

Small Intestine Structure and Function

  • The majority of digestion and absorption occurs in the jejunum section of the small intestine.
  • The duodenum is 25-30 cm in length and receives chyme from the stomach, as well as secretions from the liver, gallbladder, and pancreas.
  • The main type of epithelium found in the small intestine is simple columnar epithelium.

Small Intestine Modifications

  • The mucosa and submucosa of the small intestine have three modifications that increase its functional surface area: plicae circulares, villi, and microvilli.

Small Intestine Regions

  • The ileum is connected to the cecum of the large intestine at the ileocecal valve.
  • The jejunum has the most abundant plicae circulares.

Villi Function

  • Villi in the small intestine increase the surface area for absorption of nutrients into the bloodstream.

Small Intestine Digestion and Absorption

  • The jejunum is responsible for the completion of chemical digestion and absorption of nutrients.

Test your knowledge of the anatomy and histology of the small intestine. Learn about the different sections, their functions, and the layers that make up this crucial organ for digestion and nutrient absorption.
