Label the parts of the respiratory system using vocabulary learned.

Since I can't view or access images directly, I can't see the specific diagram you're referring to. However, based on your description — a labeled diagram of the respiratory system with numbered parts (1 through 11) and a task to label them using vocabulary — I can help you identify the correct labels for the typical structures in the human respiratory system.

Here’s a standard breakdown of the major parts of the respiratory system, which likely correspond to the numbered parts in your diagram:

---

Typical Structures in the Respiratory System (with common labeling order):

1. Nasal cavity – The entrance to the respiratory tract through the nose.
2. Mouth – Alternative entry point for air.
3. Pharynx (throat) – Passageway shared by air and food.
4. Larynx (voice box) – Contains vocal cords; connects pharynx to trachea.
5. Trachea (windpipe) – Tube leading from larynx to bronchi.
6. Right lung – One of the two lungs; right side has three lobes.
7. Epiglottis – Flap that covers the larynx during swallowing.
8. Bronchus (main bronchus) – Branches from trachea into each lung.
9. Bronchioles – Smaller branches within the lungs.
10. Alveoli – Tiny air sacs where gas exchange occurs.
11. Diaphragm – Muscular sheet below the lungs that aids breathing.

Common Vocabulary Used to Label Parts:

- Nasal cavity
- Mouth
- Pharynx
- Larynx
- Trachea
- Bronchi / Bronchus
- Bronchioles
- Alveoli
- Lungs (right and left)
- Diaphragm
- Epiglottis

How to Match the Numbers:

Assuming the diagram is a standard anterior view of the respiratory system:

1. Nasal cavity – Top of the head, above the mouth
2. Mouth – Below nasal cavity
3. Pharynx – Behind the mouth and nasal cavity
4. Larynx – Below pharynx, often shown as a box-like structure
5. Trachea – Long tube descending from larynx
6. Right lung – Right side of chest cavity
7. Epiglottis – Flap covering larynx (often near #3 or #4)
8. Bronchi – Branching tubes entering lungs from trachea
9. Bronchioles – Smaller branches inside lungs
10. Alveoli – Small clusters at end of bronchioles
11. Diaphragm – Dome-shaped muscle at base of lungs

✔ Example Answer Key:

If your diagram follows this layout:

1. Nasal cavity
2. Mouth
3. Pharynx
4. Larynx
5. Trachea
6. Right lung
7. Epiglottis
8. Bronchi
9. Bronchioles
10. Alveoli
11. Diaphragm

💡 Tip: If your diagram shows a side view or different numbering, adjust accordingly. For example, if #1 is the top of the head, it's likely the nasal cavity, and #11 at the bottom is probably the diaphragm.

Let me know if you can describe the positions of the numbers or provide the list of vocabulary words given in the exercise — I’ll help match them exactly!
