the large intestine

the large intestine

The large intestine, also known as the large bowel or colon, is the last part of the gastrointestinal tract and of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation.

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

Your large intestine is the final part of your digestive tract. Undigested food enters. It then reabsorbs water that is used in digestion and eliminates undigested food and fiber. This causes food waste products to harden and form feces, which are then excreted.


  • reabsorption of water and mineral ions such as sodium and chloride.
  • formation and temporary storage of feces.
  • maintaining a resident population of over 500 species of bacteria.
  • bacterial fermentation of indigestible materials.
