If a nineteenth century fur trapper had the stomach for this amazing tale, so can you!
This is Sandra Loh with the Loh Down on Science.
This comes thanks to scientists at a recent Experimental Biology symposium in Boston.
The subjects? trapper Alexis St. Martin and his doctor, William Beaumont.
St. Martin was accidentally shot in the stomach in 1822. He surprised everyone, including Beaumont, by surviving the ordeal. This, despite a gastric fistula . . . a permanent opening that formed when his outer wound fused with the hole in his stomach.
It was this fistula that gave Dr. Beaumont his own opening into the workings of the human digestive system.
After a skeptical St. Martin agreed, Beaumont performed 238 experiments on St. Martin’s innards over 8 years. Yikes! Some involved putting food tied to string into the fistula, then pulling it out periodically to check digestion. Ew! Among his many discoveries? Beaumont showed that hydrochloric acid is the main chemical that breaks down food.
And what about “holey” St. Martin? He actually outlived the good doctor, fistula and all.
