Frequently Asked Questions
Why do we have both a liver and a pancreas if both help digestion?
The liver produces bile to emulsify fats. The pancreas produces enzymes (amylase, protease, lipase) to break down carbohydrates, proteins, and fats respectively. Both are needed for complete digestion.
What is the purpose of the gallbladder?
The gallbladder stores and concentrates bile produced by the liver. When fatty food enters the small intestine, the gallbladder contracts and releases bile to help with fat digestion.
How long does food take to travel through the entire digestive system?
On average, food takes 24-72 hours to travel from mouth to anus. Most of this time is spent in the small intestine and colon, where digestion and absorption occur.
