The Gastro-Intestinal Tract is a tube that goes from your mouth through to your anus. It is lined with mucosa membrane the whole way through.

  • An adult oesophagus (also spelled esophagus and also called gullet) ranges from 10 to 14 inches in length, and 1 inch in diameter
  • We make 1 to 3 pints of saliva a day
  • Muscles contract in waves to move the food down the oesophagus. This means that food would get to a person's stomach, even if they were standing on their head
  • An adults stomach can hold approximately 1.5 liters of material
  • The stomach's wall is lined with three layers of powerful muscles
  • The average male will eat about 50 tons of food during his lifetime in order to sustain a weight of 150 lbs
  • Within the colon, a typical person harbors more than 400 distinct species of bacteria
  • On average, the stomach produces 2 liters of Hydrochloric Acid (HCl) daily
  • The liver is the second largest organ in the body, second only to your skin.
