The nether distances of the gastrointestinal tract are a holding chamber for what remains of a meal once the intestine has absorbed what it can of the nutrients. Water is absorbed from the digesta as it travels along, and if all goes optimally, it leaves the body around the time it’s reached a manageable water content: somewhere between 2 on the Bristol Stool Scale* (“sausage-shaped but lumpy”) and 5 (“soft blobs with clearcut edges”). The lovely upshot is that one need only attend to the emptying once or twice a day.
