Digestive Process - The Small Intestine - The Large Intestine


The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.
Outline the purpose of the :
  • Muscular walls of the small intestine : The muscular walls move food along the peristalisis.

  • Villi and Microvlli:The projections the villi and microvlli make increases the surface area of the small intestine, increasing the rate of absorption.

  • The walls of Villius: To ensure the rapid absorption into the bloodstream.


  • Capillary (blood vessel) Network inside the villius: To ensure the flow of nutrients and blood in your bloodstream.



The major function of the large intestine is to absorb water from the remaining indigestible food matter and transmit the useless waste material from the body.

Outline the purpose of the :

  • reabsorption of water and mineral ions such as sodium and chloride

  • formation and temporary storage of faeces

  • maintaining a resident population of over 500 species of bacteria

  • bacterial fermentation of indigestible materials
