- a. Small intestine
- b. Large intestine
- c. Stomach
- d. Pancreas
- e. Liver
Solution
Answer
The majority of water absorption in the gastrointestinal (GI) tract occurs in the small intestine.
Explanation:
- The small intestine plays a crucial role in digestion and nutrient absorption. It has a large surface area due to villi and microvilli, which facilitate the absorption of not only nutrients but also water.
- While the large intestine also absorbs some water, particularly to concentrate waste, most of the water is absorbed in the small intestine.
- The stomach primarily stores food and begins digestion, but it does not significantly absorb water.
- The pancreas and liver are involved in digestion and metabolism but do not absorb water directly.
Therefore, the correct answer to the question is:
Answer: a. Small intestine
