Where is water mainly absorbed in the digestive system?

The large intestine is the primary site for water absorption in the digestive system. After the small intestine has completed the majority of nutrient absorption, the remaining material, which contains a significant amount of water, passes into the large intestine. The large intestine works to reclaim this water, effectively transforming the liquid chyme into more solid waste. This process is essential for maintaining the body's fluid balance and contributes to the proper function of the digestive system.

The small intestine does absorb some water, but its main role is to absorb nutrients and vitamins. The stomach primarily focuses on breaking down food and mixing it with gastric juices but does not play a significant role in water absorption. The duodenum, while part of the small intestine, is specifically concerned with the initial digestion of food and does not primarily function in water absorption. Thus, the correct focus on the large intestine highlights its crucial role in water reclamation and overall digestive health.
