No parts of a hamburger is digested in the mouth. All food is digested in the stomach. ------------------------------------------------------------------ Not true. Saliva contains enzymes that break down starch (carbohydrates) into sugars (that is why bread begins to taste sweet when chewed. Therefore the hamburger bun will start to be digested in the mouth.
food is chewed in your molars.

Esophagus and intestines are primarily food conduits in the body. The esophagus helps transport chewed food from the mouth to the stomach, while the intestines absorb nutrients from the digested food and eliminate waste.
Most food is digested in the stomach.
The food that isn't digested is called waste.
Bolus is a mass of chewed food mixed with saliva, ready to be swallowed, while chyme is the partially digested food that passes from the stomach into the small intestine for further digestion and absorption of nutrients.
Digestion begins the instant you swallowed the food you just chewed up. Maybe not the instant but it begins when the food reaches your stomach.
Cud-chewing animals are called ruminants. Ruminants are any hoofed mammal that digests its food in two steps. In the first step, the food is chewed and partially digested in the mouth. The food is then regurgitated and chewed again (the cud). This second step allows the animal to extract more nutrients from the food. Ruminants include cattle, sheep, goats, buffalo, deer, and camels.
Because cows tend to swallow their food whole and a carrot needs to be chewed first in order to be swallowed and digested. A cow would choke if she were to eat a carrot whole.
It is digested the same way your other food are digested.
