I will tour his gastrointestinal tract and monitor the digestion of his meal and along the way. I will describe all the major structures I pass by.

Then I will trace my path from the superior mesenteric vein through the left renal artery, via the hepatic portal vein, heart and lungs, at the same time describing all the major structures that I will have pass by.

From there I will narrate what happens as I travel through the urinary tract until leaving the body via the urethra, based on my first-hand observations.

Gastrointestinal tract or also known as the alimentary canal consists of the mouth, Pharynx, esophagus, stomach, small intestine, large intestine and the anus.
