Question

Which of the following plays an important role in digestion, but is not part of the digestive system?

bladder

stomach

liver

gall bladder

Answer 1

The liver plays an important role in digestion but is not part of the digestive system in the traditional sense (e.g., mouth, esophagus, stomach, intestines). The liver produces bile, which aids in the digestion of fats, and it also processes nutrients absorbed from the digestive tract.
