What are the activities of absorption that occur in the large intestine? Describe the movement of food residue through the large intestine that results in watery, liquid stools
?Some nutrient and water absorption occurs in the large intestine. The colon wall secretes mucus as a protection from the acidic digestive juices in the chyme. The major functions of the large intestine are to absorb water, synthesize some B vitamins and vitamin K, and collect food residue. Undigested food is excreted as feces by way of the rectum. If diarrhea is present, this means the chyme and liquids have moved through the colon too rapidly to be absorbed; therefore, a liquid stool results, with little water or nutrient absorption taking place.
