Which of the following organs is not an accessory organ of the digestive system? (A) Gallbladder (B) Brain (C) Liver (D) Pancreas
Answer (1)
In the context of the digestive system, accessory organs are those that assist in the digestive process but are not part of the main digestive tract. The main organs of the digestive tract include the mouth, esophagus, stomach, small intestine, and large intestine. The accessory organs secrete enzymes or other substances that aid in digestion.
Let's look at the options provided in the question:
Gallbladder : This organ stores and concentrates bile produced by the liver. It releases bile into the small intestine to help digest fats. The gallbladder is indeed an accessory organ of the digestive system.
Brain : The brain is not involved in the digestive process as an accessory organ. While it does play a role in hunger signaling and other regulatory functions, it does not secrete substances that aid in digestion. Therefore, the brain is not considered an accessory organ of the digestive system.
Liver : This vital organ produces bile, which is crucial for the digestion and absorption of fats in the small intestine. The liver is certainly an accessory organ of the digestive system.
Pancreas : The pancreas produces digestive enzymes and bicarbonate, which help to further digest food as it enters the small intestine. It also plays a role in regulating blood sugar. The pancreas is classified as an accessory organ of the digestive system.
Considering these explanations, the correct answer is (B) Brain . The brain is not an accessory organ of the digestive system, unlike the gallbladder, liver, and pancreas.
