The digestive system is composed of the gastrointestinal tract—commonly referred to as the GI tract or digestive tract—as well as the liver, pancreas, and gallbladder. The gastrointestinal system is made up of a succession of hollow organs connected by a long, twisting tube that runs from the mouth to the anus. The mouth, esophagus, stomach, small intestine, large intestine, and anus are the hollow organs that comprise the GI tract. The liver, pancreas, and gallbladder are the digestive system’s solid organs (NIDDK, 2019).

ileum
This cross section of the human ileum kinda looks like a small dragon to me too. Function-wise, the ileum helps absorb nutrients like vitamin B12 and bile salts before passing the rest to the large intestine. The villi really do most of the work here.
