Which of the following is NOT a term associated with the digestive system?

The bladder is not associated with the digestive system; instead, it is part of the urinary system. The primary functions of the bladder include storing urine until it is excreted from the body.

On the other hand, the other terms—esophagus, stomach, and anus—are all integral components of the digestive system. The esophagus is the tube that connects the throat to the stomach, facilitating the movement of food. The stomach is a key organ in the digestive process where food is broken down and mixed with digestive juices. The anus, as the final part of the digestive tract, is responsible for expelling waste material from the body. This clear distinction in function and system categorization highlights why the bladder does not belong in the context of digestive terms.
