Science: Label the digestive system | Worksheet | PrimaryLeap.co.uk - Free Printable

Let's solve this step-by-step.

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

Our task is to label the correct parts of the digestive system in the diagram using these words.

Step 1: Identify the parts of the digestive system based on their location in the body.

Let’s go through each labeled line and match it with the correct organ.

#### 1. Top left (near the head)
- The first box points to the mouth.
- This is where food enters the body.
✔ Label: mouth

#### 2. Just below the mouth, going down the neck
- This tube connects the mouth to the stomach.
- It is the oesophagus.
✔ Label: oesophagus

#### 3. The large sac-like organ just below the oesophagus
- This is the stomach, where food is mixed with gastric juices.
✔ Label: stomach

#### 4. A green organ above the stomach
- This is the liver, which produces bile for digestion.
✔ Label: liver

#### 5. A small yellow sac next to the liver
- This is the gallbladder, which stores bile.
✔ Label: gallbladder

#### 6. A long, coiled tube extending from the stomach
- This is the small intestine, where most digestion and nutrient absorption occur.
✔ Label: small intestine

#### 7. The large, wide tube surrounding the small intestine
- This is the large intestine, which absorbs water and forms feces.
✔ Label: large intestine

#### 8. A gland near the stomach and small intestine
- This is the pancreas, which produces enzymes and hormones like insulin.
✔ Label: pancreas

#### 9. Inside the mouth, on the floor
- This is the tongue, used for tasting and moving food.
✔ Label: tongue

Final Labels (from top to bottom, left to right):

1. Mouth – top left, near the lips
2. Oesophagus – tube from mouth to stomach
3. Stomach – below oesophagus
4. Liver – above stomach, on the right side
5. Gallbladder – small yellow sac under the liver
6. Pancreas – behind the stomach, connecting to small intestine
7. Small intestine – coiled tube from stomach
8. Large intestine – outer ring around small intestine
9. Tongue – inside the mouth

Completed Diagram Labels (in order of boxes):

1. mouth
2. oesophagus
3. stomach
4. liver
5. gallbladder
6. pancreas
7. small intestine
8. large intestine
9. tongue

> ✔ Note: The tongue is labeled last because it's inside the mouth, so it's connected to the mouth area.

Summary:

Use the word bank to fill in the blanks as follows:

- First blank (top left): mouth
- Second blank (top right): oesophagus
- Third blank (middle left): stomach
- Fourth blank (middle right): liver
- Fifth blank (below liver): gallbladder
- Sixth blank (below gallbladder): pancreas
- Seventh blank (bottom left): small intestine
- Eighth blank (bottom right): large intestine
- Ninth blank (inside mouth): tongue

✔ All labels are now correctly matched to the diagram.
