This worksheet helps students identify and label key organs of the human digestive system, such as the stomach and liver, using a provided word bank.

Let's solve this step-by-step.

Task: Label the Digestive System Diagram

We are given a diagram of the human digestive system and a word bank with the following terms:

Word Bank:
- large intestine
- stomach
- tongue
- pancreas
- oesophagus
- mouth
- gallbladder
- liver
- small intestine

We need to match each label to the correct part of the digestive system shown in the diagram.

Step 1: Identify the parts of the digestive system based on their position and function

Let’s go through the diagram from top to bottom and identify each structure:

1. Mouth – This is where food enters the body. It’s at the very top, near the lips and teeth.
2. Tongue – Located inside the mouth, it helps in chewing and swallowing.
3. Oesophagus (Esophagus) – The tube that connects the mouth to the stomach.
4. Stomach – A J-shaped organ below the oesophagus; it breaks down food.
5. Liver – A large organ located above the stomach, on the right side.
6. Gallbladder – A small green sac beneath the liver; stores bile.
7. Pancreas – Located behind the stomach, near the duodenum (first part of the small intestine).
8. Small Intestine – Coiled tube that extends from the stomach; absorbs nutrients.
9. Large Intestine – Surrounds the small intestine; absorbs water and forms feces.

Step 2: Match labels to the diagram

Now, let’s assign each term to the correct blank line in the diagram:

1. Top left: This points to the mouth → Mouth
2. Top right: Points to the pink tube going down → Oesophagus
3. Middle left: Points to the stomach → Stomach
4. Below stomach, on the right: Points to the liver → Liver
5. Just below liver, small green sac: Points to the gallbladder
6. Below gallbladder, behind stomach: Points to the pancreas
7. Coiled tube under stomach: Points to the small intestine
8. Outer loop around small intestine: Points to the large intestine
9. Inside mouth, pink muscle: Points to the tongue

Wait — we have 9 blanks, but only 9 words. Let's check the lines:

Looking at the diagram:
- There are 9 labeled lines pointing to different organs.
- We must use all 9 words.

Let’s list them again in order from the diagram:

1. Line pointing to the mouth → Mouth
2. Line pointing to the tongue → Tongue
3. Line pointing to the oesophagus → Oesophagus
4. Line pointing to the stomach → Stomach
5. Line pointing to the liver → Liver
6. Line pointing to the gallbladder → Gallbladder
7. Line pointing to the pancreas → Pancreas
8. Line pointing to the small intestine → Small intestine
9. Line pointing to the large intestine → Large intestine

✔ Final Answer:

Label the blanks in order (from top to bottom):

1. Mouth
2. Tongue
3. Oesophagus
4. Stomach
5. Liver
6. Gallbladder
7. Pancreas
8. Small intestine
9. Large intestine

> Note: The exact order depends on how the lines are drawn. But typically, the layout follows:
>
> - Top: Mouth
> - Next: Tongue (inside mouth)
> - Then: Oesophagus
> - Stomach
> - Liver (on right)
> - Gallbladder (under liver)
> - Pancreas (behind stomach)
> - Small intestine
> - Large intestine

But since the image shows 9 lines, and 9 organs, you just need to match each one correctly.

🟩 Summary of Labels:

| Line Number | Organ |
|-------------|------------------|
| 1 | Mouth |
| 2 | Tongue |
| 3 | Oesophagus |
| 4 | Stomach |
| 5 | Liver |
| 6 | Gallbladder |
| 7 | Pancreas |
| 8 | Small intestine |
| 9 | Large intestine |

✔ All words used exactly once.

🔍 Explanation:

This diagram teaches students about the human digestive system. Each organ plays a role:
- Mouth & tongue: Start digestion by chewing and mixing food.
- Oesophagus: Moves food to the stomach via peristalsis.
- Stomach: Breaks down food with acids and enzymes.
- Liver: Produces bile to help digest fats.
- Gallbladder: Stores bile.
- Pancreas: Produces digestive enzymes and bicarbonate.
- Small intestine: Main site of nutrient absorption.
- Large intestine: Absorbs water and forms waste.

This labeling exercise reinforces understanding of anatomy and function.
