2 Lab 6 Activities Identify parts of the respiratory system Respiratory tree, thoracic organs, and larynx modelsFresh lung (if available)Examine histology of the:TracheaLungExamine the operation of the lung modelBiopac L012-Lung-1: SpirometryMeasure lung volumes and capacities
3 Respiratory System Structure Conduction zone: pathway for pulmonary ventilationRespiratory zone: membrane for gas exchange external respirationClinically, two parts:Upper respiratory tractLower respiratory tract
4 Respiratory System Structure Histology reflects the different functions of the different parts of the systemPosition in respiratory pathway determines cell typenon-keratinized stratified squamouspseudostratified ciliated columnarcuboidal ciliatedsimple squamous / Type I Alveolar cells
15 Spirometry: Calibration InletInletInsert the calibration syringe/filter assembly into the side of the airflow transducer labeled "Inlet." Follow pop up window instructionsWait for 8 seconds of no air flow,Then do your 5 syringe cycles.
16 Experimental Treatments 4 normal breathsInhale as deeply as possibleExhale to normal depth3 normal breathsExhale as much as possibleInhale as much as possibleExhale as fast and completely as possible
17 BioPac Spirogram Example Data If you get a negative value, just put the absolute value.This part is in addition to what Biopac Lesson 12-Lung 1 prompts you to do!1 regular exhale1 strongestinhale3 regularbreaths1 strongestinhale1 strongest exhale3 regularbreaths3 regularbreaths1 strongest exhale

23 Record your data in Excel at the computer located at the front podium Summary of Class DataRecord your data in Excel at the computer located at the front podiumYour Instructor will make the complete data set available for you to use while completing the homework assignment
24 Homework Complete and turn in the questions on pages 6-19 to 6-22 Don’t forget to print the entire spirogram (landscape format) you recorded to include in your lab report.Use vertical brackets ( [ ] ) to identify and label the tidal, inspiratory reserve, expiratory reserve and residual volumes; and total lung, vital, expiratory and inspiratory capacities on your spirogram.Lab 6-21, Question 4. Use a scatterplot, not a line graph!Remember to completely label your graphs!Complete Assignment 6 on MasteringAandP.
