Feces are made in the colon/large intestine, then pass through the rectum and then the anus.
The function of the rectum in the fetal pig is the same as in humans. It is the final 6" of the colon and acts as a warehouse for fecal matter.
The noise when you pass gas from the rectum is generated by the movement of the gas passing through the anus. The volume of gas and the force with which it is expelled produces the vibrations. Some people learn to control the sphincter muscles and can expel the gas in small volumes thus producing little or no noise at all.

Food passes through your entire digestive tract before it reaches your rectum. That means that food goes into your esophagus, then your stomach, then your small intestine, and then your large intestine before it reaches your rectum.
It travels from the stomach and intestines down through your colon, into the rectum, and out the anus.
