The rectum doesn't do anything to break down food. By the time "food" reaches the large intestine, what was at one time "food" is then liquefied waste. In the small intestines, fluid is added. So in the large intestines, the fluid is pulled back out of the waste and then pushed toward the kidneys to process it. As the fluid is pulled back, the liquefied wastes become semi-solid (to very dry solid if constipated). After going through the last part of the large intestines, the solid waste (stool, feces) is pushed into the top of the rectum. The rectum acts as a holding receptacle and as a nerve center that sets off a "gotta go" signal through a feeling of fullness, e.g. pressure on the nerves in the walls of the rectum. The rectum is about 10-12cm in length. So it can hold a lot of waste. Also, because the intestines and rectum are basically round tubes, resulting in us having a mostly rounded stool (unless we end up with too much water left in the waste, resulting in diarrhea. As you can see, the rectum has nothing to do with breaking down food.

How does a beetle digest food?
Beetles digest food through a process that begins in their mouth, where they chew and break down the food with their mandibles. The food then travels down the esophagus to the crop, where it can be stored, and then into the gizzard, which further grinds it. Digestion continues in the midgut, where enzymes break down nutrients, which are absorbed into the bloodstream. Finally, undigested material is expelled through the rectum as waste.
