Activity 1: Respiratory System Lab
1. Launch the view!
• If you’re already in AR mode: point your camera* at the image below.
• If you’re not in AR mode:• Open Visible Body Suite.
• Search for and select the view “Respiratory System.”•Launch AR mode.

2. Fill in the blanks.
• Find the structures listed in the word bank.
• Read the definitions, then fill in the blank with the correct respiratory system structure from theword bank.

Word bank:• Alveoli• Nasopharynx• Bronchi• Oropharynx• Laryngopharynx• Primary bronchi• Lungs• Trachea• Nasal cavityThe ______________________________ is composed of the chambers of the internal nose that function
as a part of the upper respiratory system.
The ______________________________ is the most posterior part of the pharynx. It is shared by therespiratory system and the digestive system. The upper respiratory and upper digestive tracts
diverge right after this structure. The front of this structure merges with the triangular entranceof the larynx.
The ______________________________ conveys air between the upper and lower respiratory
structures.
The ______________________________ is a portion of the pharynx that begins at the rear of the nasal
cavity and functions as an airway in the upper respiratory system. Its cavity always stays open,
unlike the other parts of the pharynx.
The ______________________________ are two organs that are responsible for gas exchange.
The ______________________________ are the major airways of the lower respiratory system.
The ______________________________ are the main sites of gas exchange, where oxygen is brought
into the bloodstream and carbon dioxide is removed.
The ______________________________ is a portion of the pharynx that is shared by the respiratory
system and the digestive system. It functions as an airway in the upper respiratory system.
The ______________________________ are the major airways of the lower respiratory system. They link
the trachea with the right and left lungs. They are wrapped in rings of hyaline cartilage, and theirinteriors are lined with mucous membrane.

Activity 3: Respiratory System Lab
1. Learn about respiration!
• Read the articles on the respiratory system: https://www.visiblebody.com/learn/respiratory.
• Fill in the blanks in the following statements.
I­n ______________________________, air is inhaled through the nasal and oral cavities (the nose andmouth). Air moves through the pharynx, larynx, and trachea into the lungs. Then, it is exhaled,flowing back through the same pathway.
Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called______________________________. This respiratory process takes place through hundreds of millionsof microscopic sacs called ______________________________.
The bloodstream delivers oxygen to cells and removes waste carbon dioxide through______________________________.

Activity 4: Respiratory System Lab
1. Launch the view!
• If you’re already in AR mode: point your camera at the image below.
• If you’re not in AR mode:• Open Visible Body Suite.
• Search for and select the view “Alveolar Sacs.”•Launch AR mode.

2. Label the image.
• Explore the 3D model of the alveolar sacs to locate the anatomy in the structure list.
• Use the structure list to label the image.

Alveoli are microscopic air sacs that are home to the main function of the respiratory system:
carrying out gas exchange to bring oxygen into the body and remove carbon dioxide.
Structure list:
1. Alveolus

4. Pulmonary artery

7. Respiratory bronchiole

2. Alveolar cavities

5. Pulmonary capillary beds

8. Terminal bronchiole

3. Bronchiolar smooth muscle

6. Pulmonary vein
