From which organ do digestive enzymes enter the small intestine?

• A. Kidney
• B. Pancreas
• C. Spleen
• D. Liver

Answer: (B)

Digestive enzymes that actively break down carbohydrates, proteins, and fats come from the pancreas and are released into the small intestine as pancreatic juice. These enzymes, such as amylase, proteases (like trypsin), and lipase, travel through the pancreatic duct into the duodenum where they mix with chyme to aid digestion. The liver produces bile, which helps emulsify fats but does not provide digestive enzymes; the spleen and kidneys do not secrete digestive enzymes into the GI tract. So, the organ supplying these digestive enzymes entering the small intestine is the pancreas.
