Educational worksheet on the digestive system for students to complete.

I'll solve this worksheet by filling in the blanks with the correct words from the word bank. Let me go through each blank step by step.

First, I need to understand what this worksheet is asking for. It's about "The Digestive System" and requires me to use words from the word bank to fill in the blanks. The word bank contains: 1. fluids, 2. energy, 3. food, 4. nutrients, 5. saliva, 6. chemical, 7. stomach, 8. waste, 9. mouth, 10. energy, 11. fuel, 12. intestine, 13. absorption, 14. cells, 15. esophagus, 16. sugars.

Let me work through the text:

1. "All living things need _____, the energy the body needs comes from the _____ it eats."
- The first blank should be "energy" (word #2 or #10)
- The second blank should be "food" (word #3)

2. "The parts of the body that help break down the food it eats and turn it into _____ for digesting food to _____ all of the _____ in the body."
- The first blank should be "nutrients" (word #4)
- The second blank should be "fuel" (word #11) or possibly "provide"
- The third blank should be "cells" (word #14)

3. "Digesting takes two forms, mechanical and _____ ."
- This should be "chemical" (word #6)

4. "Your mouth does the chewing which is referred to as mechanical digestion and your _____ and intestines break the food down using chemicals turning it into _____ which is called chemical digestion."
- The first blank should be "stomach" (word #7)
- The second blank should be "sugars" (word #16) or "nutrients" (word #4)

5. "First, the food is broken down by chewing and being softened by the _____ in the mouth."
- This should be "saliva" (word #5)

6. "From there, it is then swallowed by the _____ in the throat and passes through to the stomach."
- This should be "esophagus" (word #15)

7. "The stomach acid and gastric juices change the swallowed foods into _____ and turns it into nutrients that the body needs."
- This should be "fluids" (word #1)

8. "After the stomach, the food then enters the small intestine where the nutrients are absorbed."
- This is already filled correctly.

9. "From the small intestine, the nutrients reach the blood stream by _____ where they nourish the cells in the body."
- This should be "absorption" (word #13)

10. "What is left over then travels to the large intestine where most of the water is removed from the food. What remains is then turned into solid _____ to be taken to the rectum for excretion."
- This should be "waste" (word #8)

Now I'll compile the complete answer with the correct numbers from the word bank:

All living things need 2, the energy the body needs comes from the 3 it eats. The parts of the body that help break down the food it eats and turn it into 4 for digesting food to 11 all of the 14 in the body. The digestive system is responsible for digesting food to 11 all of the 14 in the body. Digesting takes two forms, mechanical and 6. Your mouth does the chewing which is referred to as mechanical digestion and your 7 and intestines break the food down using chemicals turning it into 16 which is called chemical digestion. First, the food is broken down by chewing and being softened by the 5 in the mouth. From there, it is then swallowed by the 15 in the throat and passes through to the stomach. The stomach acid and gastric juices change the swallowed foods into 1 and turns it into nutrients that the body needs. After the stomach, the food then enters the small intestine where the nutrients are absorbed. From the small intestine, the nutrients reach the blood stream by 13 where they nourish the cells in the body. What is left over then travels to the large intestine where most of the water is removed from the food. What remains is then turned into solid 8 to be taken to the rectum for excretion.
