Which organ in the digestive system has a function that is most similar to the function of a bladder in the excretory system

Answer 1

The organ in the digestive system that has a function most similar to the function of a bladder in the excretory system is the gallbladder. The gallbladder stores and concentrates bile produced by the liver until it is needed for digestion. Similarly, the bladder in the excretory system stores and holds urine until it is ready to be expelled from the body.
