Which organ is considered part of the gastrointestinal tract?

Spleen
Heart
Gallbladder
Lungs

The correct answer is: Gallbladder

The gallbladder is considered part of the gastrointestinal (GI) tract because it plays a crucial role in the digestion process as a storage site for bile, which is produced by the liver. Bile is important for the emulsification and absorption of fats in the small intestine, which is a key part of the GI tract. While the gallbladder itself is not directly involved in the movement of food, it is functionally associated with the digestive system, delivering bile to the small intestine when needed. The other options listed are not part of the GI tract. The spleen is primarily involved in the immune response and the filtration of blood, the heart is part of the circulatory system responsible for pumping blood, and the lungs are involved in respiration. Each of these organs has important functions, but they do not contribute to the digestive processes that characterize the gastrointestinal tract.
