The large intestine is primarily involved in protein digestion.
B
The pancreas produces bile to aid in digestion.
C

Verified step by step guidance1
Begin by understanding the roles of different organs in the mammalian digestive system. The digestive system is responsible for breaking down food, absorbing nutrients, and eliminating waste.
Consider the function of the large intestine. It is primarily involved in absorbing water and electrolytes, not protein digestion. Protein digestion mainly occurs in the stomach and small intestine.
Examine the role of the pancreas. The pancreas produces digestive enzymes and hormones like insulin, but it does not produce bile. Bile is produced by the liver and stored in the gallbladder.
Evaluate the function of the stomach. The stomach is involved in the initial digestion of proteins and mixing food with gastric juices, but it is not the primary site for nutrient absorption. Nutrient absorption mainly occurs in the small intestine.
Identify the role of the small intestine. The small intestine is responsible for most nutrient absorption, including carbohydrates, proteins, fats, vitamins, and minerals. It is equipped with structures like villi and microvilli to increase surface area for absorption.
