ANAT II Lab 6 Respiration 9
Lab 6. Respiratory System Mechanics-14 Name ______
Purpose: This lab explores the mechanics and factors which affect the process of pulmonary ventilation, the exchange of gases between the outside of body and the lungs.
Materials: Physio Ex CD 9.0
Procedure: Complete the activities on Respiratory System Mechanics in the lab manual. Read the lab and answer the questions, some of which do not come from the lab manual, and submit. Keep in mind this lab involves pulmonary ventilation.
Part I. Answer the following questions on structure.
1. What type of tissue lines the inside of the trachea? What is the function of this tissue?
2. What is the function of the cilia?
3. What type of cartilage is found in the trachea?
4. What is the function of the trachea?
5. How are the alveoli structurally ideal for their function?
6. How are Boyles and Charles’ Laws used to describe ventilation?
7. How does help explain how much oxygen is carried in the blood?
8. If there is an increase in the partial pressure of carbon dioxide, then the amount of carbon dioxide found in the blood will: (increase, decrease, not change.)
Part II. Using the 9.0 CD, complete the lab and answer the following questions:
Chart I Respiratory Volumes and Capacities
Radius (mm)
Flow (mL/min)
TV (mL)
ERV (mL)
IRV (mL)
RV (mL)
VC (mL)
FEV (mL)
TLC (mL)
1. Activity 1 Measuring Respiratory Volumes and Calculating Capacities
Activity Questions:
1. When you forcefully exhale your entire expiratory reserve volume, any air remaining in your lungs is called the residual volume (RV). Why is it impossible to further exhale the RV (that is, where is this air trapped, and why it is trapped)?
2. How do you measure a person’s RV in the laboratory?
Activity 2. Comparative Spirometry
Chart 2 Spirometry Results
