2. 2. Match the words or terms to their definition. Write the number of the term next to the correct definition.

1. Gas exchange         __________________  Force exhalation more than normal
2. Oxyhemoglobin     __________________normal amount of air taken  in during breathing
3. Carbonate ion        __________________amount of air remaining in the lungs
4. Spirometer             __________________Most oxygen molecules will carried  as that.
5. Tidal volume           __________________The overall amount of air the lungs can  accommodate
6. ERV                           __________________Most carbon dioxide will be transported as that.
7. Vital capacity           __________________the main function of respiration
8. Residual volume     __________________amount that can be inhaled above normal breathe.
9. Total lung capacity  __________________required for measuring TV, IRV and ERV

3     a. Write the chemical reaction which takes place during carbon dioxide loading (from tissue to blood).

b.  Write the chemical reaction which takes place during carbon dioxide unloading (from
blood to alveoli).

c.  How are the reactions related?

d.  What is the name of the enzyme required for the reaction to occur?

 

4. The vital capacity of a patient is about 4800 ml. He has an IRV of 3,100 ml. What is the ERV, assuming the TV is normal?

 

5. Calculate the total lung capacity if IRV is 3100 ml, ERV 2000 ml, TV is 590 ml and RV is 1200 ml.

 

6. Calculate the IRV if VC is 6100, ERV is 1200 ml, and TV is 520.

2.    IRV ___________________
3.    ERV ___________________
4.    RV ___________________
5.    VC ___________________
6.  TLC ___________________

 

 

7. 8.  Label the following volumes and capacities. Give the normal volume for each. (Do an internet or book search)
