People do not ruminate, ruminants are some even-toed animals, such as cows, giraffes and so on. They will eat after a period of time, the stomach half-digested food back to the mouth to chew again. This type of digestion is called ruminating.
The human digestive system consists of the alimentary canal and the digestive glands. After the food is chewed and ground in the mouth, it is brought into the stomach by the esophagus, where it undergoes preliminary digestion and is transformed into chyme. Coeliac contraction peristalsis through the stomach by the pylorus into the small intestine, and in the small intestine, fully digested and absorbed, with the peristalsis of the small intestine will continue to push the coeliac downward, to the end of the small intestine, the coeliac nutrients in the majority of the nutrients are absorbed.
The food residue reaches the large intestine through the ileocecal valve, and the large intestine absorbs the water and inorganic salts in the food to form feces, which is finally discharged from the anus.
So people don’t ruminate.
