In 1822, an American soldier named Alexis St. Martin was accidentally shot in the stomach at close range. Surprisingly, St. Martin survived and became a walking experiment for an army doctor, William Beaumont. The hole in Alexis’ abdomen never healed properly, so Beaumont could actually look in and study the digestive process as it happneed. With Alexis’ consent, Beaumont carried out a series of experiments through this hole, lasting nine years. Beaumont could press on the abdomen above the liver and obtain yellow liquid through the hole. He also removed an analysed stomach contents.
