Which of the following is NOT listed as a digestive system organ?

Explanation:
The key idea is to distinguish which organs belong to the digestive system. Stomach, liver, and pancreas are involved in digestion—stomach acids and enzymes break down food, the liver produces bile to help digest fats, and the pancreas releases digestive enzymes into the small intestine. The heart, however, is part of the circulatory system and pumps blood throughout the body, not involved in breaking down or processing food. Therefore, the heart is not a digestive system organ.
