Label the digestive system worksheet for Year 4 Science, featuring a human body diagram and a word bank for labeling organs.

Let’s go step by step to label the digestive system correctly.

We have a diagram of the human digestive system with 9 blank boxes pointing to different organs. We also have a word bank with these words:

- large intestine
- stomach
- tongue
- pancreas
- oesophagus
- mouth
- gallbladder
- liver
- small intestine

We need to match each word to the correct part in the diagram.

Step 1: Start from the top — where food enters.

The very first box on the top left points to the mouth — that’s where eating starts.

The box on the top right points to the tongue, which is inside the mouth and helps chew and push food down.

Step 2: Below the mouth, there’s a long tube going down — that’s the oesophagus (also called esophagus). It carries food from the mouth to the stomach.

Step 3: The next big organ below the oesophagus is the stomach — it looks like a J-shaped bag. That’s where food gets churned with acid.

Step 4: To the right of the stomach (on the person’s left side), there’s a large brown organ — that’s the liver. It makes bile to help digest fats.

Step 5: Just under the liver, there’s a small green sac — that’s the gallbladder. It stores bile from the liver.

Step 6: Behind the stomach, there’s a yellowish organ — that’s the pancreas. It makes enzymes and insulin.

Step 7: Now, the coiled tubes in the middle — those are the small intestine. Food goes here after the stomach to get most nutrients absorbed.

Step 8: Surrounding the small intestine is a thicker tube — that’s the large intestine. It absorbs water and forms poop.

Now let’s assign the labels based on position:

Top left box → mouth

Top right box → tongue

Middle left (first box) → oesophagus

Middle left (second box) → liver

Middle left (third box) → gallbladder

Middle left (fourth box) → pancreas

Bottom left (fifth box) → small intestine

Wait — we have 9 boxes total. Let’s count again:

Actually, looking at the diagram layout:

Left side has 5 boxes vertically.

Right side has 4 boxes vertically.

Total = 9 boxes.

Let’s map them carefully:

Left column (top to bottom):

1. Points to mouth → mouth

2. Points to oesophagus → oesophagus

3. Points to liver → liver

4. Points to gallbladder → gallbladder

5. Points to small intestine → small intestine

Right column (top to bottom):

1. Points to tongue → tongue

2. Points to stomach → stomach

3. Points to pancreas → pancreas

4. Points to large intestine → large intestine

Yes — that uses all 9 words.

Final matching:

Left side (top to bottom):
- mouth
- oesophagus
- liver
- gallbladder
- small intestine

Right side (top to bottom):
- tongue
- stomach
- pancreas
- large intestine

All words used once. Perfect.

Final Answer:
mouth, tongue, oesophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine
