Label the respiratory system (worksheet) - Free Printable

To solve the problem of labeling the diagram of the respiratory system, we need to identify and place the correct terms from the provided word bank into the appropriate locations on the diagram. Below is a step-by-step explanation of how to label the diagram correctly.

Step 1: Understand the Diagram

The diagram shows the human respiratory system, which includes key structures such as the nose, throat, lungs, and other related parts. The task is to match the labels with the corresponding parts in the diagram.

Step 2: Identify Key Structures

Here are the main components of the respiratory system that are typically labeled in such diagrams:

1. Nose - The entry point for air.
2. Mouth - Another entry point for air.
3. Pharynx (Throat) - The passageway connecting the nasal cavity and mouth to the larynx.
4. Larynx (Voice Box) - Contains the vocal cords.
5. Trachea (Windpipe) - The tube that carries air to and from the lungs.
6. Bronchi - The two main branches of the trachea leading to the lungs.
7. Lungs - The primary organs of respiration where gas exchange occurs.
8. Diaphragm - A muscle that helps in breathing by expanding and contracting the chest cavity.
9. Alveoli - Tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged.

Step 3: Match Labels to the Diagram

Using the above information, let's assign the labels to the diagram. Assume the word bank contains the following terms (if not explicitly provided):

- Nose
- Mouth
- Pharynx
- Larynx
- Trachea
- Bronchi
- Lungs
- Diaphragm
- Alveoli

#### Labeling the Diagram:
1. Top Left: Nose - This is the structure at the top of the head where air enters.
2. Top Right: Mouth - Located below the nose, another entry point for air.
3. Middle Left: Pharynx - The area connecting the nose and mouth to the larynx.
4. Middle Center: Larynx - Just below the pharynx, containing the vocal cords.
5. Middle Right: Trachea - The long tube extending downward from the larynx.
6. Lower Left: Bronchi - The two main branches of the trachea leading to the lungs.
7. Lower Center: Lungs - The large, spongy organs where gas exchange occurs.
8. Bottom Center: Diaphragm - The dome-shaped muscle beneath the lungs.
9. Tiny Air Sacs in Lungs: Alveoli - These are not explicitly shown but are part of the lungs.

Final Answer:

Based on the typical layout of such diagrams, the labels should be placed as follows:

1. Top Left: Nose
2. Top Right: Mouth
3. Middle Left: Pharynx
4. Middle Center: Larynx
5. Middle Right: Trachea
6. Lower Left: Bronchi
7. Lower Center: Lungs
8. Bottom Center: Diaphragm

If the word bank provides additional terms or if the diagram has specific areas marked, adjust the labels accordingly.

Boxed Final Answer:

\[
\boxed{
\text{Nose, Mouth, Pharynx, Larynx, Trachea, Bronchi, Lungs, Diaphragm}
}
