PART I - A spirometer is used to measure air flow and volume, as well as the oxygen and carbon dioxide content, into and out of the mouthpiece. The subjects are instructed to hold their breath after breathing in and out. Occasionally, the subject is asked to perform an inspiration or expiration (apnea) during the experiment. Towards the end of the experiment, the subject is instructed to rapidly breathe in and out (like a panting dog). Please answer the following questions using the data: Flow Shallow Rapid Respiration Inspiration Apnea Expiration Apnea Volume 1.) Describe the relationship between %O2 and %CO2 in the graph. What does this have to do with gas exchange in the alveoli, and how can we use these two graphs to determine when inspiration and expiration is occurring?

Drawing Conclusions Measurements of Ventilation Fill in the blanks to complete the following sentences about measuring lung capacity. Then follow the instructions to create a spirographic record. Use a pencil to create the waveform so that you can alter it as needed to complete each step. 1. The amount of air inhaled and exhaled during quiet breathing is known as _____________. In a healthy young adult, this measurement is typically _____________ mL. (Create a spirographic record in the rectangle below. Begin by inserting a waveform showing the measurement described in sentence 1. Use the numbers along the left of the rectangle as a guide. Color the area on the spirographic record indicative of this measurement blue. In other words, highlight the area behind the waveform blue. Write the name of the measurement in the blue area.) 2. The amount of air inhaled using maximum effort after a normal inspiration is called the _____________ _____________ volume. This amount is typically _____________ mL. (Alter the waveform to include this reading. Color the area on the spirographic record indicative of this measurement green; write the name of the measurement in the green area.) 3. The amount of air that can be exhaled after a normal expiration using maximum effort is the _____________ _____________ volume. This amount is typically _____________ mL. (Alter the waveform to include this reading. Color the area on the spirographic record indicative of this measurement orange and write the name of the measurement in the orange area.) 4. The amount of air remaining in the lungs after a forced expiration is called the _____________ _____________. This amount is about _____________ mL. (Color the area on the spirographic record indicative of this measurement pink; write the name of the measurement in this pink area.) 5. The amount of air that can be inhaled and exhaled with the deepest possible breath is the _____________ _____________. This number can be obtained by adding the tidal volume to the _____________ and _____________ volumes. (Draw a bracket around the part or parts of the waveform that indicates this measurement. Label the bracket with the name of the measurement.) 6. The maximum amount of air that the lungs can contain is called the _____________. (Draw a second bracket around the part or parts of the waveform that indicate this measurement. Label the bracket with the name of the measurement.) 6000 5000 4000 3000 2000 1000 0 Lung volume (mL)

00:01 Hello everyone so over here when we talk about the first question the relationship between the %o2 yes and the %co2 in the graph typically shows an inverse relationship.

00:21 So when the %o2 will increase the %co2 will decrease and the vice versa.

00:29 Okay this relationship is associated with gas exchange in the alveoli.

00:37 Fine then when we talk about the second one that is during the inspiration yes when we talk about the inspiration the %o2 rises as the oxygen is taken in and the %co2 will decrease as the co2 carbon dioxide is removed from the body...
