Is the GI system the digestive system?

Yes, the gastrointestinal (GI) system is commonly referred to as the digestive system. It includes a series of organs such as the mouth, esophagus, stomach, intestines, and anus, which work together to break down food, absorb nutrients, and eliminate waste. While the GI system specifically refers to the tract that processes food, it also encompasses accessory organs like the liver, pancreas, and gallbladder that aid in digestion.
