Worksheet Respiratory System - Free Printable

Let me work through this step by step.

Step 1: Identify the respiratory organs shown
Looking at the images at the bottom, I can see:
- A diaphragm (the curved red muscle)
- A nose
- Lungs with trachea/windpipe
- A mouth

Step 2: Determine where each organ goes in the body outline

For the diaphragm: This is a dome-shaped muscle located below the lungs, separating the chest cavity from the abdomen. It should be placed in the lower chest/upper belly area of the body outline.

For the nose: This goes on the face/head area of the body outline, in the center of where the face would be.

For the lungs with trachea: The lungs are in the chest cavity. The trachea (windpipe) connects to them from above. These should be placed in the upper/middle chest area of the body outline.

For the mouth: This goes on the face/head area, below where the nose would be positioned.

Step 3: Labeling
Each organ needs to be labeled with its name:
- Diaphragm
- Nose
- Lungs (or Lungs and Trachea)
- Mouth

Step 4: Verify the placement makes sense
The respiratory system works by air entering through the nose or mouth → traveling down the trachea → into the lungs → with the diaphragm helping to expand and contract the lungs for breathing. This order from top to bottom (nose/mouth → trachea → lungs → diaphragm) makes anatomical sense.

Final Answer:
Place the organs in the body outline as follows:
1. Nose - on the face area (center of head)
2. Mouth - on the face area (below the nose)
3. Lungs with trachea - in the chest area (upper torso)
4. Diaphragm - below the lungs (lower chest/upper abdomen area)

Label each organ with its name: Nose, Mouth, Lungs, and Diaphragm.
