Here are 10 fun facts about the digestive system:

1. The largest organ in your digestive system is your small intestine.

1. Your stomach can hold about 2 pints of food and liquid. However, it doesn’t store food for very long. Food typically leaves the stomach within 2-4 hours of eating.
2. The small intestine is responsible for absorbing most of the nutrients from your food. It has a huge surface area, thanks to millions of tiny folds called villi. If you unrolled your small intestine, it would be about 20 feet long!
3. Your liver produces about 600 gallons of bile per day. Bile is a fluid that helps to break down fats in your food.
4. Your gallbladder stores and concentrates bile. When you eat a fatty meal, your gallbladder releases bile into the small intestine to help digest it.
5. The large intestine absorbs water from food and stores waste products. It also contains trillions of bacteria, which help to digest food and protect your body from disease.
6. Your digestive system is controlled by your nervous system. Your brain and spinal cord send signals to your digestive organs to tell them when to contract and relax. This helps to move food through your digestive system and break it down into nutrients that your body can use.
7. You can eat upside down. Food is moved through your digestive system by peristalsis, which is a wave-like motion of your muscles. Gravity doesn’t play a role in this process, so you can eat upside down and food will still travel to your stomach.
8. Your stomach growls when it’s empty. This is caused by the gas moving around in your stomach.
9. Your stomach contains a layer of mucus that protects it from acid.
