Why food is completely digested in duedunem?

Answer 1

Food is primarily digested in the duodenum because it is the first section of the small intestine where digestive enzymes and bile are introduced. The pancreas secretes digestive enzymes that break down carbohydrates, proteins, and fats, while bile from the liver emulsifies fats, making them easier to digest. This combination of enzymes and bile facilitates the complete digestion of food particles into absorbable nutrients. As a result, by the time food passes through the duodenum, most of the digestion is accomplished before moving to the jejunum for nutrient absorption.
