Respiratory system exercise - Free Printable

The task is to label the parts of the respiratory system in the provided diagram. Below is the solution with an explanation:

Diagram Analysis:

The image shows a side view of a human figure with labeled parts of the respiratory system. The labels are numbered (1, 2, 3, 4, 5), and there are corresponding terms listed on the right side of the image (NOSE, MOUTH, TRACHEA, BRONCHI, LUNGS). The goal is to match the correct term to each numbered part.

Solution:

1. Part 1: This is the opening at the top of the head.
- Label: NOSE

2. Part 2: This is the opening at the front of the face below the nose.
- Label: MOUTH

3. Part 3: This is the tube that connects the throat to the lungs.
- Label: TRACHEA

4. Part 4: These are the branching tubes that lead into the lungs.
- Label: BRONCHI

5. Part 5: These are the main organs of the respiratory system where gas exchange occurs.
- Label: LUNGS

Final Answer:

- Part 1: NOSE
- Part 2: MOUTH
- Part 3: TRACHEA
- Part 4: BRONCHI
- Part 5: LUNGS

Explanation:

The respiratory system is responsible for breathing, which involves inhaling oxygen and exhaling carbon dioxide. Here’s how the labeled parts function:
1. NOSE/MOUTH: Air enters the body through the nose or mouth. The nose filters, warms, and humidifies the air.
2. TRACHEA: Also known as the windpipe, it carries air from the throat to the lungs.
3. BRONCHI: These are the main airways that branch off from the trachea into the lungs.
4. LUNGS: These are the primary organs where oxygen is absorbed into the bloodstream, and carbon dioxide is removed.

By matching the anatomical structures in the diagram to their correct names, we can accurately label the respiratory system.

Final Answer Boxed:
\[
\boxed{\text{1. NOSE, 2. MOUTH, 3. TRACHEA, 4. BRONCHI, 5. LUNGS}}
