Step 1: Understand the Respiratory System Pathway

Air enters the body through the nose or mouth, then travels down through the following structures:

1. Nasal cavity / Nose
2. Pharynx (throat)
3. Larynx (voice box)
4. Trachea (windpipe)
5. Bronchi (which branch into the lungs)
6. Lungs (where gas exchange occurs)
7. Diaphragm (muscle that helps with breathing)

Step 2: Identify Each Labeled Part

Now, let’s go through each arrow and determine which organ it points to:

#### Top Right Arrow → Nasal Cavity / Nose
- The arrow points to the nose.
- This is where air enters the respiratory system.
- ✔ Answer: Nose

#### Left Side Arrow → Pharynx
- The arrow points to the throat area, just below the nose and mouth.
- This is the pharynx, a common passage for food and air.
- ✔ Answer: Pharynx

#### Curved Arrow → Larynx
- The curved arrow points to the voice box, located below the pharynx.
- This is the larynx, which contains vocal cords.
- ✔ Answer: Larynx

#### Arrow Pointing to Left Lung → Left Lung
- The arrow points to the left side of the lung.
- ✔ Answer: Left Lung

#### Arrow Pointing to Right Lung → Right Lung
- The arrow points to the right side of the lung.
- ✔ Answer: Right Lung

#### Bottom Arrow → Diaphragm
- The arrow points to the dome-shaped muscle beneath the lungs.
- This is the diaphragm, which contracts and relaxes to help with breathing.
- ✔ Answer: Diaphragm

Final Answers:

Fill in the gaps as follows:

1. Top Right Box: Nose
2. Left Box (Pharynx): Pharynx
3. Right Box (Larynx): Larynx
4. Left Lung Box: Left Lung
5. Right Lung Box: Right Lung
6. Bottom Box (Diaphragm): Diaphragm
