Respiratory System Lab Report
Name, date, course and section required for password:
The lab report is unique each semester and checks have been put into place to ensure students are doing their own work. Copying from other students or from outside sources will result in a zero on the accompanying lab quiz.
I. Human Respiratory Anatomy
1. Explain the connection of functions between the respiratory system and the circulatory system.
A. Anatomy of Human Respiratory System
1. Examine the diagrams of the upper respiratory system and add a location and function of each respiratory structure:
    Structure
    Location
    Function of Upper Respiratory Structures
    Nasal cavity
    
    
    Hard palate
    
    
    Soft palate
    
    
    pharynx
    
    
    epiglottis
    
    
    larynx
    
    
    Vocal cords
    
    
    Trachea o
windpipe
    
    
2. Look through the diagrams of the lower respiratory system and add a description of each respiratory structure.

    Bronchioles
    
    Alveoli ducts
    
    Alveoli
    
    Lungs

    External intercostals
    
    External intercostals
    
B. Alveolar Tissue
1. In Ex 3, look at the microscopic view of an alveolus. Explain what might happen if the alveoli space was filled with fluid.
II. Fetal Pig Anatomy
1. What is the path of air after the nostrils?
2. In the fetal pig why are the lungs flat and deflated?
3. Label the parts of the fetal pig thoracic cavity below.
    A.
    
    B.
    
    C.
    
    D.
    
    E.
    
III. Ventilation
1. Read through A Inspiration, B Expiration, and C Pressure Relationships in the Thorax and fill out the comparison of inspiration and expiration.

2. In EX 6, view the Bell jar demonstration. What part of the bell jar co
esponds to your lungs?
3. What happens in the bell jar when the diaphragm E moves down?
IV. Spirometry
A. Lung Volumes and B. Lung Capacities- refer to spirogram
1. Complete the chart comparing 4 mutually exclusive lung volumes and two lung capacities
    A. Lung Volume
    Explanation
    Average volume ml
    Tidal Volume (TV)
    
    
    Inspiratory Reserve Volume (IRV)
    
    
    Expiratory Reserve Volume (ERV)
    
    
    Residual Volume (RV)
    
    
    B. Lung Capacities
    Formula for this capacity
    Total
    Vital Capacity (VC)
    
    
    Total Lung Capacity (TLC)
    
    
2. Ex 8, complete the data table of the 12 students:

View the video demonstration of a spirometer. Construct a graph showing the relationship between vital capacity (Y axis) and age
(X axis) for all 12 students. Label your axes. Sign, date, and prepare an image of your graph, and include it with your lab report.
INSERT YOUR GRAPH HERE
a. From your graph what is the relationship of VC to age?
. Is there a co
elation of VC to height?
c. Is there a co
elation of VC to sex (gender)?
d. Is there a co
elation to smoking?
V. Control of respiration
1. If you are “winded” and have to stop and “catch your
eath” you have a buildup of what gas in the blood?
2. This is the most important stimulus that controls
3. Ex 9, follow instructions and record your results below:
    Activity Steps 1-4
    Ave.#
eathes/min
    CO2 levels up, down, same
    1. Respiratory rate at rest
    
    
    2. Hyperventilation
    
    
    3. Hold your
eath, record how long in seconds
    
    
    4. Run in place 2 min.
then hold
eath, record how long in seconds
    
    
Summary Questions
1. Follow the path of
eath from nostrils to alveoli and name the respiratory structures that comprise the airway.
2. Where is the interface between the respiratory and circulatory systems and what happens at that site?

3. What is the location and function of the diaphragm?
4. Name the four lung volumes which, when combined, give the total lung capacity.
