Part 1: Review of the Respiratory System
1. Put the following structures in order as indicated by each part a. and b. below:
|
|
|
a. Put the structures in order air passes through from entry into the respiratory system to the point of gas exchange with the blood (this order follows the path of O2 into the body):
|
1. ____________________ 2. ____________________ 3. ____________________ 4. ____________________ 5. ____________________ 6. ____________________ 7. ____________________ 8. ____________________ 9. ____________________ |
10.____________________ 11.____________________ 12.____________________ 13.____________________ 14.____________________ 15.____________________ 16.____________________ 17.____________________ 18.____________________ |
b. Put the structures in order air passes through from gas exchange with the blood to its exit from the respiratory system (this order follows the path of CO2 out of the body):
|
1. ____________________ 2. ____________________ 3. ____________________ 4. ____________________ 5. ____________________ 6. ____________________ 7. ____________________ 8. ____________________ 9. ____________________ |
10.____________________ 11.____________________ 12.____________________ 13.____________________ 14.____________________ 15.____________________ 16.____________________ 17.____________________ 18.____________________ |

Part 2: Examining the Histology of the Respiratory System
- Obtain the slides listed below that are available for today’s lab.
- Focus on each sample and identify the structures listed for each type of tissue.
- Indicate the total magnification you make each illustration at in the space provided.
- Illustrate each tissue you observe with the microscope at the magnification you listed.
- Label each illustration with the structures listed for each.
Trachea Cross Section
Illustrations at more than one magnification will be required.
Label the tissue with: trachea, esophagus, cartilage ring, opening in cartilage ring, lumen, pseudostratified ciliated columnar epithelium, goblet cells, cilia, basement membrane, lamina propria, elastic lamina, mixed glands, hyaline cartilage
Lung Tissue
More than one illustration will required with more than one magnification.
Label the tissue with: secondary bronchi, cartilage plates, pulmonary blood vessels, bronchioles, terminal bronchiole, respiratory bronchiole, alveolar ducts, alveoli, type I alveolar cells, interalveolar septum, endothelium, pulmonary capillary, connective tissue, alveolar lumen
Part 3: Mechanism of Breathing (Balloon-and-Bell Jar Model)
Materials
- Balloon-and-bell jar
Instructions & Questions
- Pull down the rubber sheet. What happens to the balloons? ___ .
- This represents the downward movement of the human __ , which causes the chest cavity to become _______ (larger/smaller). This, in turn, causes the human _ _____ to expand and fill with air.
- Release the rubber sheet. What happens to the balloons?______________.
- This represents relaxed __________ (inhaling/exhaling), when the chest cavity becomes smaller and the lungs deflate. Note that this is a passive process.
- What organs do the balloons represent? __________________
- What does the rubber sheet you pulled on represent? ____________________
