Saliva moistens ingested food and it become a slick semisolid material called

The answer to this question would be: bolus

The food that chewed by the teeth will become semisolid and mixed the saliva, called bolus. Bolus will be ingested and sent to the gaster/stomach. In the stomach, the bolus will be digested again with the gastric juice and the gaster movement. After about 2 hours, the food will be passed into the intestine. 

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
