Question

Which part of the alimentary canal is involved in the reabsorption of water and minerals from undigested food?

• A. Oesophagus
• B. Large intestine
• C. Small intestine
• D. Stomach

Answer 1

The correct option is B Large intestine

The small intestine receives the secretion from the liver, pancreas, and intestine. Thus, it is the site for the complete digestion of carbohydrates, proteins, and fats.
In the small intestine, the digested food is absorbed through finger-like projections called villi and undigested food is pushed into the large intestine.
Then, water and minerals are absorbed from the undigested food in the large intestine.
