Year 4 Science: Animals, including humans- digestion, teeth and ... - Free Printable

Let's solve this step-by-step based on the image you've described. The task involves:

1. Labeling the parts of the digestive system in the diagram.
2. Coloring each part according to the color code provided.
3. Completing a table with the function of each part.

🔹 Step 1: Label the Diagram

From the diagram (a human body showing the digestive tract), here are the labeled parts corresponding to the numbers:

1. Mouth – where food enters the body
2. Tongue – helps chew and mix food
3. Oesophagus (Esophagus) – tube that carries food from mouth to stomach
4. Stomach – muscular organ that breaks down food
5. Small Intestine – absorbs nutrients from digested food
6. Large Intestine – absorbs water and forms feces

So, fill in the blanks:
- 1. Mouth
- 2. Tongue
- 3. Oesophagus
- 4. Stomach
- 5. Small Intestine
- 6. Large Intestine

🔹 Step 2: Color Each Part

Use the color codes given:

| Part | Color |
|-----------------|------------|
| Mouth | Pink |
| Tongue | Red |
| Oesophagus | Orange |
| Stomach | Green |
| Small Intestine | Blue |
| Large Intestine | Purple |

Color accordingly on the diagram.

🔹 Step 3: Complete the Table – Functions in Digestion

Now, write the function of each part:

| Part | Function in Digestion |
|------------------|------------------------|
| Mouth | Breaks down food by chewing (mechanical digestion) and mixes it with saliva (beginning of chemical digestion). |
| Tongue | Helps chew food, mixes it with saliva, and pushes food into the oesophagus during swallowing. |
| Oesophagus | Transports food from the mouth to the stomach via peristalsis (muscular contractions). |
| Stomach | Mixes food with gastric juices to break it down further (chemical digestion); churns food into chyme. |
| Small Intestine | Main site of nutrient absorption; completes digestion with enzymes and absorbs nutrients into the bloodstream. |
| Large Intestine | Absorbs water and electrolytes from indigestible food matter; forms and stores feces. |

✔ Final Answer Summary

#### 🔤 Labels for Diagram:
1. Mouth
2. Tongue
3. Oesophagus
4. Stomach
5. Small Intestine
6. Large Intestine

#### 🎨 Colors:
- Mouth → Pink
- Tongue → Red
- Oesophagus → Orange
- Stomach → Green
- Small Intestine → Blue
- Large Intestine → Purple

#### 📋 Completed Table:

| Part | Function in Digestion |
|------------------|------------------------|
| Mouth | Begins mechanical and chemical digestion by chewing and mixing food with saliva. |
| Tongue | Chews and mixes food; aids in swallowing. |
| Oesophagus | Transports food from mouth to stomach via muscle contractions. |
| Stomach | Breaks down food using acids and enzymes; converts food into chyme. |
| Small Intestine | Completes digestion and absorbs nutrients into the blood. |
| Large Intestine | Absorbs water and forms feces for elimination. |

This completes both the labeling, coloring, and functional understanding of the digestive system as required in the worksheet!
