Q11Which of the following digestive system organs is primarily responsible for the absorption of nutrients during digestion?
✓ Correct answer: B. Small intestine
Answer: Small intestine The digestive system includes organs specialized in breaking down food, absorbing nutrients, and expelling waste. The principal organs are the mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas, and gallbladder. The small intestine is responsible for the absorption of most nutrients derived from digested food. It has three sections: the duodenum, jejunum, and ileum. The walls of the small intestine contain villi that help increase the surface area for nutrient absorption. The stomach aids in breaking down food through mechanical and chemical digestion. The large intestine absorbs water and electrolytes, forming and excreting solid waste. The liver produces bile, which helps digest fats but is not directly involved in nutrient absorption.
