Trace the Journey

Use your word-find terms and what you know about digestion to answer each clue. Give full explanations where asked.

2.Tui takes a bite of an apple. Which substance in the mouth begins chemical digestion, and what type of nutrient does it start breaking down?

3.After swallowing, food travels down a muscular tube to the stomach. Name the tube and explain how peristalsis helps move food along.

4.Nathan says, “The stomach is where all digestion happens.” Is he correct? Choose the best response.

Yes; the stomach completes every stage of digestion.
No; digestion also happens in the mouth and small intestine.
Yes; food is absorbed directly through the stomach wall.
No; the stomach has no role in digestion.

5.The liver makes bile, which is stored in the gall bladder and released into the small intestine. What does bile do to fats, and is this chemical digestion by an enzyme?

6.Match each structure or substance to its role. Write the correct letter beside each number.

1. Pancreas
2. Villi
3. Small intestine
4. Rectum

D. Stores faeces before they leave the body
A. Finger-like projections that increase the small intestine’s absorptive surface
B. Adds digestive enzymes to the small intestine
C. Main site where digested nutrients pass into the blood

7.Explain why the small intestine has a very large surface area. Include the word villi and describe what is absorbed.

8.An enzyme in the small intestine breaks large protein molecules into smaller molecules. What is the name of the smaller molecules, and why must food be broken down before absorption?

9.Put these stages in order by writing 1–4: nutrients absorbed in the small intestine; food enters the mouth; food is churned in the stomach; faeces are stored in the rectum.

10.True or false: Most water is absorbed in the large intestine, while the small intestine absorbs most digested nutrients. Correct the statement if needed.

TrueFalse

11.A sanctuary visitor claims that digestion and absorption mean the same thing. Explain the difference in one or two sentences.
