Let's solve this step-by-step based on the diagram and the labels provided.

Step 1: Identify each labeled organ (A to O) in the digestive system diagram

We will match each letter (A–O) with its correct organ, then assign it to the list of organs numbered 1–15.

Here’s the breakdown:

- D – Mouth (includes tongue and salivary glands)
- E – Salivary Glands
- F – Epiglottis
- G – Esophagus
- C – Liver
- B – Gallbladder
- A – Pancreas
- H – Stomach
- I – Duodenum (first part of small intestine)
- J – Jejunum/Ileum (small intestine — J is likely ileum or jejunum)
- K – Colon (large intestine)
- L – Rectum
- M – Anus
- N – Appendix
- O – Caecum

Now let’s map them correctly to the numbered list.

Step 2: Match the letters to the numbered list

| Number | Organ | Letter |
|--------|-------------------|--------|
| 1. | Colon | K |
| 2. | Anus | M |
| 3. | Tongue | D |
| 4. | Epiglottis | F |
| 5. | Salivary Glands | E |
| 6. | Liver | C |
| 7. | Gallbladder | B |
| 8. | Anus | M |
| 9. | Appendix | N |
| 10. | Esophagus | G |
| 11. | Stomach | H |
| 12. | Pancreas | A |
| 13. | Duodenum | I |
| 14. | Ileum (small intestine) | J |
| 15. | Caecum | O |

> Note: "Anus" appears twice (2 and 8), which may be a mistake in the worksheet, but both should be M.

Step 3: Answer the Question: What are the right foods to eat for our growth and development?

This is an open-ended question, but here’s a well-rounded answer suitable for students:

> To support growth and development, we should eat a balanced diet that includes:
>
> - Proteins (like eggs, milk, beans, meat) – help build muscles and repair tissues.
> - Carbohydrates (like rice, bread, potatoes) – provide energy.
> - Fruits and vegetables – rich in vitamins and minerals for strong immunity and healthy body functions.
> - Dairy products (milk, cheese, yogurt) – supply calcium for strong bones and teeth.
> - Healthy fats (like nuts, avocados, olive oil) – essential for brain development and energy.
> - Water – keeps the body hydrated and helps in digestion and nutrient transport.
>
> Eating a variety of these foods ensures that our bodies get all the nutrients needed for healthy growth and development.
