Label Digestive System worksheet - Free Printable

Let's solve the Digestion Labeling Activity step by step.

We are given a diagram of the human digestive system with blank labels and a list of organs to choose from:

Organs to label:

- oesophagus
- anus
- liver
- mouth
- small intestine
- large intestine
- pancreas
- stomach

---

Now, let’s identify where each organ is located in the diagram based on standard human anatomy:

1. Mouth – At the top of the diagram, where food enters.
2. Oesophagus – The tube going down from the mouth to the stomach.
3. Stomach – A J-shaped organ below the esophagus.
4. Liver – Located on the upper right side (from the person's perspective), above the stomach.
5. Pancreas – Lies behind the stomach, near the duodenum (first part of the small intestine).
6. Small intestine – Coiled structure beneath the stomach; it's longer and more tightly coiled.
7. Large intestine – Surrounds the small intestine; wider and forms a loop around it.
8. Anus – At the bottom end of the digestive tract.

Step-by-step labeling:

Now, match each label to the correct box using the lines pointing to the organs:

#### Left side (from top to bottom):
1. Top left: Points to the mouth → mouth
2. Middle left: Points to the oesophagus → oesophagus
3. Bottom left: Points to the small intestine → small intestine

#### Right side (from top to bottom):
1. Top right: Points to the liver → liver
2. Middle right: Points to the pancreas → pancreas
3. Bottom right: Points to the large intestine → large intestine

#### Bottom center:
- The line pointing to the very end of the digestive tract → anus

Wait — actually, there are two boxes at the bottom: one on the left and one on the right. Let’s recheck:

Looking closely:
- The bottom left box points to the rectum/anus area.
- The bottom right box also points to the same area? Or is it the large intestine?

But the large intestine wraps around the small intestine, so the bottom right box likely points to the large intestine, and the bottom left points to the anus.

Actually, let’s trace carefully:

From the image:
- The bottom left line goes to the anus.
- The bottom right line goes to the large intestine (the lower part).

So final assignment:

Final Answer:

| Box Position | Correct Label |
|---------------------|---------------------|
| Top left | mouth |
| Middle left | oesophagus |
| Bottom left | anus |
| Top right | liver |
| Middle right | pancreas |
| Bottom right | large intestine |
| Middle center (stomach) | stomach |
| Small intestine | small intestine |

Wait — we have 8 organs and 8 boxes.

Let’s count the boxes:

There are 8 blank boxes:
- 3 on the left
- 3 on the right
- 2 at the bottom (one on each side)

And the organs listed are:
- mouth
- oesophagus
- stomach
- liver
- pancreas
- small intestine
- large intestine
- anus

Now, assign based on typical diagram:

1. Top left → mouth
2. Middle left → oesophagus
3. Bottom left → anus
4. Top right → liver
5. Middle right → pancreas
6. Bottom right → large intestine
7. Stomach → This is the big J-shaped organ — it should be labeled from the middle of the diagram, but no line directly points to it? Wait…

Wait — actually, looking again: there is a line from the middle of the diagram pointing to the stomach, and another pointing to the small intestine.

Let’s re-express:

The lines are drawn from the boxes to the organs:

- One line goes from top left → mouth
- One line from middle left → oesophagus
- One line from bottom left → anus
- One line from top right → liver
- One line from middle right → pancreas
- One line from bottom right → large intestine
- One line from center-left → stomach
- One line from center-right → small intestine

Yes! There are two central lines — one pointing to the stomach, one to the small intestine.

So now, correct labeling:

Final Matching:

| Box Location | Organ Labeled |
|----------------------|---------------------|
| Top left | mouth |
| Middle left | oesophagus |
| Bottom left | anus |
| Top right | liver |
| Middle right | pancreas |
| Bottom right | large intestine |
| Center-left (stomach)| stomach |
| Center-right (intestine) | small intestine |

✔ Final Answer:

Label the boxes as follows:

- Top left: mouth
- Middle left: oesophagus
- Bottom left: anus
- Top right: liver
- Middle right: pancreas
- Bottom right: large intestine
- Center-left: stomach
- Center-right: small intestine

Explanation:

This activity tests knowledge of the human digestive system. Each organ plays a specific role:
- Mouth: Begins digestion with chewing and saliva.
- Oesophagus: Transports food to the stomach via peristalsis.
- Stomach: Mixes food with gastric juices.
- Liver: Produces bile for fat digestion.
- Pancreas: Produces digestive enzymes and bicarbonate.
- Small intestine: Main site of nutrient absorption.
- Large intestine: Absorbs water and forms feces.
- Anus: Exit point for waste.

By correctly labeling the diagram, students reinforce understanding of digestive anatomy.

✔ All labels are now correctly matched!
