the answer is PERISTALSIS...
Isa did this and your welcome it was in my science homework
the pyloric sphincter regulates the speed at which the chyme (mixture of food from stomach) can enter into the small intestine to be digested. The pyloric sphincter opens and closes according to the acidity of the chyme.
peristalsis slows down the large intestante
slows down the passage of the food slomg the intestines, and afford an increased surface for absorption. Increase the surface area for the intestines to increase absorption of nutrients

Alcohol is absorbed primarily in the intestines. Therefore, keeping alcohol in the stomach (by eating food) slows its release into the intestines and therefore, its absorption into the blood stream.
General anesthesia stops or significantly slows the movement of your intestines. As the anesthesia wears off, the trapped gas or bowel begin to move through the intestines again. Occasionally this can be a very painful process. So just know that this is a common feeling after general anesthesia.
Most opiates are agonists of the mu opiod receptors. These are found both in the brain and in the gut. When they activate the receptors in the gut, it causes paralysis of the intestines and slows down peristalsis.
The drug loperamide, found in Imodium A-D, for example, slows the passage of stools through the intestines. This allows more time for water and salts in the stools to be absorbed back into the body.

Of course it's possible for a pregnant woman to have diarrhea; however, it is more common for a pregnant woman to suffer from constipation, as the child and uterus grow and put pressure on her intestines and slows her digestive system.
When the river hits the sea and slows down, hence why a large number of rivers have sedimentary deltas at the mouth
