The Digestive System
• We eat about 500kg of food per year
• It takes around 1 to 2 days for food to travel thru your entire digestive system.
• The average person has over 400 different species of bacteria in their colon
• The liver has over 500 different functions
• Food is cooled or warmed in the mouth until it is a good temperature for the body
• Muscles contract and relax in the esophagus to push food down to the stomach — it works even when you’re upside down!
