You are basically referring to the same thing, which is water absorption. Small intestine absorbs 7-9 L of water per day.
Large intestine absorbs about 300 ml per day in order to dehydrate the waste.
The mechanism and purpose of water absorption is different in 2 intestines.
The small intestine absorbs water from ingestion as well as secretory glands, while large intestine absorbs water to dehydrate waste for normal excretion.

Hope this helps.

I remember a question long time back that asked where does most water reabsorption took place and the answer was large intestine. Not sure if the question was worded this way or not.

thats exactly why I asked... because small intestine absorbs water the MOST but I recall the answer's question was Large Intestine...
