Explain what happens to food when it enters the mouth

When food enters the digestive system through the mouth ... Food is then broken into smaller pieces just by a person chewing. The teeth then cut and also crush the food, While the food is mixed with saliva. The process of this basically helps to makes it soft and a lot more easier for a person to swallow food.

I hope this helps you :)

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
