#16 – Gallbladder
The gallbladder is a minuscule organ in the shape of a pear that’s found below the liver. The only function of this tiny organ is storing and releasing bile produced by the liver into intestines. However, a person can comfortably live without its gallbladder.
We featured gallbladder on this list of useless organs because it’s prone to various infections, ailments, as well as painful gallstones which bring unbearable pain to their sufferers. And do we have to mention that gallbladder cancer is probably the worst type of cancer after melanoma?
