Answers
Answer:
Your tongue helps out, pushing the food around while you chew with your teeth. When you're ready to swallow, the tongue pushes a tiny bit of mushed-up food called a bolus (say: BO-luss) toward the back of your throat and into the opening of your esophagus, the second part of the digestive tract.
Digestion, sequence by which food is broken down and chemically converted so that it can be absorbed by the cells of an organism and used to maintain vital bodily functions. This article summarizes the chemical actions of the digestive process.
Food enters the digestive system through the mouth. Food is broken down into smaller pieces by chewing. The teeth cut and crush the food, while it's mixed with saliva. This process helps to make it soft and easier to swallow.
