cholecystokinin is the hormone
cholecystokinin (CCK)
Nicotien or anything chemical which stimulates the Nicotinic receptors.
Acetylcholine
The nutrient that is not digested but stimulates intestinal muscle contractions is fiber. Fiber is a type of carbohydrate that may be soluble or insoluble.
Oxytocin
Oxytocin
Cholecystokinin
Bilirubin is used by the liver, to make bile

It works by blocking the action of progesterone, a hormone needed for pregnancy to continue, then stimulates ulerine contractions thus ending the pregnancy
The hormone that stimulates contractions of the uterus in mammals is oxytocin. However, the story is probably rather more complex. In mice, for example, that had no cell membrane receptors for oxytocin, birth took place as usual. Oxytocin has a short peptide molecule consisting of just nine amino acids.
The digestion of triglycerides in the small intestine is catalyzed by the hormone CCK (Cholecystokinin) which stimulates the gallbladder to secret bile. The bile emulsifies the triglycerides.
