A digestive story: Fill in the blanks below to complete the digestive steps. After entering grandma’s house and smelling the delicious cookies she had baking, the digestive story began. First, when I smelled the cookies my mouth began to “water” as it is sometimes called. That water is actually my ________________________, which has an enzyme in it called __________________________ that works with my teeth to chew and break down my cookies so that I can swallow them. Once I do swallow the cookies they travel through my __________________________ where my_________________________ pushes the partially digested food into my _____________________________. All this work so that I can eat a cookie! Now that the cookie is in my stomach, there are ______________________ juices that will begin to break down my food even further. That juice will break down the food so much that it turns into a mush called _________________________. Next, that substance will travel into my ______________________ intestine where it is broken down even further. With the help of the “3 juice cocktail”, consisting of _______________________________, _____________________, and _________________________. Now the food is really broken down. Some of this digested food will leave the body by traveling through the ________________________ intestine into the anus, and the rest of the digested food will be absorbed through the ________________ and travel through the ______________________vein into the ______________________ where it is distributed where ever it is needed in the body as nutrients.
