The material passing into the large intestine consists of water with undigested matter , largely cellulose and vegetable fibres ( roughage ) , mucus and dead cells from the lining of the alimentary canal .
- The large intestine secretes no enzymes but the bacteria in the colon digest part of the of the fibre to form fatty acids which the colon can absorb .
- Bile salts are also absorbed and returned to the liver by the blood circulation .
- The colon also absorbs much of the water from the undigested residues .
About 7 litres of digestive juices are poured into the alimentary canal each day . If the water from these was not absorbed by the ileum and colon , the body awould soon be dehydrated .
- The semi-solid waste , the faeces or 'stool' , is passed into the rectum by peristalsis and is expelled at intervals through the anus . The act of expelling the faeces is called Egestion or Defecation .
So simply , there is almost no digestion , mostly reabsorbtion of water and bile .
What else can I help you with?
What does the large intestine have to do with the digestion process?
The large intestine in the human body has to do with the digestion process because it has a job to absorb all the salt and liquid of the food. Hope this helps!
Does the digestion process begin with the large intestine mouth small intestine or stomach?
The digestion process begins in the mouth.
Where does the digestion process begin and end?
Digestion begins in the mouth and ends in the large intestine.
In what organ in waste from the digestion process collected for disposal?
The large intestine.
What process takes place in the large intestine?
It absorbs all the calcium.
What is the site of final digestion?
In a human's digestive tract, the final site of digestion is the small intestine.
Is the large Intestine a mechanical or a chemical digestion?
As far as I know there is no digestion at all in the large intestine, only absorption.
What bacteria helps digestion in the large intestine?
The human microbiome ~ see related link below .
Much of the digestion that occurs in the large intestine is caused by?
The digestion that occurs in the large intestine is mainly caused by the action of gut bacteria. These bacteria help break down and ferment undigested food particles, producing essential nutrients and gases like methane and hydrogen. This process also plays a role in the absorption of water and electrolytes.
Why Digestion does not occur in large intestine?
Minor fiber digestion by bacteria goes on in the large intestine, and water is absorbed, but no major lipid/protein/carbohydrate digestion occurs. All of that goes on higher up in the system.
Is the large intestine mechanical digestion or chemical?
The large intestine is mechanical digestion; it absorbs water and is involved in peristalsis. It has nothing to do with enzymes, which is chemical digestion.
Where does the digestion occur in the body?
It starts in your mouth and ends in your large intestine.
