Respiratory System for Kids (Diagram + Theory + Vocabulary) - Free Printable

Let's solve the task in the image step by step.

Task:

Complete the gaps in the diagram of the human respiratory system with the correct organ names.

The organs to be labeled are:
- Nose
- Larynx
- Trachea
- Lungs
- Bronchus
- Diaphragm

We will identify where each label goes based on the diagram and descriptions provided.

Step-by-step Analysis:

#### 1. Top of the head – Nasal cavity (Nose)
- The first arrow points to the nose.
- This is clearly labeled in the description as the first organ of the respiratory system.
- ✔ Label: NOSE

#### 2. Below the nose, leading down the throat – Larynx
- The second arrow points to the structure just below the nose, in the neck.
- This is the larynx, also known as the voice box.
- It connects the nasal passage/throat to the trachea.
- ✔ Label: LARYNX

#### 3. Long tube going down from the larynx – Trachea
- The third arrow points to the long tube extending from the larynx down into the chest.
- This is the trachea or windpipe.
- Described as a tube connecting the larynx to the lungs.
- ✔ Label: TRACHEA

#### 4. Two large structures in the chest – Lungs
- The fourth arrow points to the two large red organs on either side of the chest.
- These are the lungs, where gas exchange occurs.
- ✔ Label: LUNGS

#### 5. Branches inside the lungs – Bronchus
- There’s an arrow pointing to the branching tubes *inside* the lungs.
- These are the bronchi (singular: bronchus), which branch off from the trachea into the lungs.
- ✔ Label: BRONCHUS

#### 6. Muscle at the bottom of the lungs – Diaphragm
- The last arrow points to the dome-shaped muscle beneath the lungs.
- This is the diaphragm, which helps control breathing by contracting and relaxing.
- ✔ Label: DIAPHRAGM

Final Answer (Labels for the Diagram):

From top to bottom:

1. NOSE → (top arrow, pointing to the nose)
2. LARYNX → (second arrow, in the neck)
3. TRACHEA → (third arrow, vertical tube)
4. LUNGS → (fourth arrow, left and right lung)
5. BRONCHUS → (fifth arrow, inside the lung branches)
6. DIAPHRAGM → (bottom arrow, under the lungs)

Summary of Labels:

| Arrow Position | Organ Name |
|----------------|----------------|
| Top | Nose |
| Neck | Larynx |
| Down the throat | Trachea |
| Left & Right | Lungs |
| Inside lungs | Bronchus |
| Bottom | Diaphragm |

✔ All labels are correctly matched to their anatomical positions.

This activity helps reinforce understanding of the respiratory system’s anatomy and function. You can also use the information provided in the pink boxes to create a revision flashcard or mnemonic for memory retention!
