To determine which organ is not part of the digestive system, we need to first understand what constitutes the digestive system.

The digestive system is a collection of organs that work together to break down food into nutrients that can be absorbed by the body. It includes the mouth, esophagus, stomach, small intestine, large intestine, pancreas, liver, and gallbladder.

To find the organ that is not part of the digestive system, we need to compare this list of organs to the possible options. Here are some common organs:

1. Heart: The heart is not part of the digestive system. It is responsible for pumping blood and is part of the circulatory system.

2. Lungs: Lungs are also not part of the digestive system. They are involved in the process of respiration and belong to the respiratory system.

3. Kidneys: The kidneys are not part of the digestive system either. They play a vital role in filtering waste products from the blood and are part of the urinary system.

4. Liver: The liver is indeed part of the digestive system. It produces bile, which helps in the breakdown of fats, and also processes nutrients absorbed by the intestines.

Based on the above information, the organ that is NOT part of the digestive system is the "Heart."
