Detailed explanation-1: -Absorption of ingested water and most solutes occurs in the proximal small intestine, therefore the rate at which beverages are emptied from the stomach is an important factor in determining the rate of water absorption.
Detailed explanation-2: -The ileum is where most of the nutrients from your food are absorbed before emptying into the large intestine.
Detailed explanation-3: -By the time indigestible materials have reached the colon, most nutrients and up to 90% of the water has been absorbed by the small intestine.
Detailed explanation-4: -Virtually all nutrients from the diet are absorbed into blood across the mucosa of the small intestine. In addition, the intestine absorbs water and electrolytes, thus playing a critical role in maintenance of body water and acid-base balance.
Detailed explanation-5: -The middle part of your small intestine is the jejunum. The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins.
