Which statement describes a major digestive function of the liver?

• A. Produces bile and participates in metabolism and detoxification.
• B. Stores urine before excretion.
• C. Filters blood as the primary urine organ.
• D. Produces insulin to regulate blood sugar.

Answer: (B)

The liver’s major digestive role is to produce bile, which is essential for fat digestion because bile emulsifies fats, making them easier for enzymes to break down. In addition to bile production, the liver participates in metabolism and detoxification: it processes nutrients absorbed from the digestive tract, helps regulate blood sugar by storing glycogen and converting it back as needed, and detoxifies or neutralizes drugs and toxins for elimination. The other statements describe functions of other organs—the bladder stores urine, the kidneys filter blood to form urine, and the pancreas produces insulin. So the liver’s key digestive function centers on bile production plus its metabolic and detoxification activities.
