Respiratory

Activity 1: Measuring Respiratory Volumes

Data: No chart necessary here, but you will need to use the data you get from running the experiments to answer the questions below

Questions: answer each question; use full sentences; ask instructor if you need help

1-1: Compute the minute respiratory volume (MRV) using the following formula:

MRV = TV X BPM (breaths per minute)

MRV=7500ml/min

1-2: Does expiratory reserve volume include tidal volume? Explain your answer.

Yes , because the tidal volume is what being given off .

Summary:

In this Activity, I learned/observed that
