Gastrointestinal

Upper Tract:

The oral cavity leads to the pharynx and the oesophagus, which terminates in the stomach

Lower Tract

After this, the duodenum joins onto the stomach, and then leads to the jejunum and then the ileum.

The large intestine starts when the ileum joins onto the caecum. The appendix also attaches to the caecum, further down. The caecum joins onto the ascending colon, then the transverse, and finally the descending colon.

At the end of this, the colon meets the rectum, which joins onto the anus.
