Unit 11: Physiology of Human Body Systems – Assignment 2 The Structure and Function of the Respiratory System Task 1 Collect measurements of peak flow from twenty different individuals. Ideally this should be 10 males and 10 females. Calculate the mean peak flow and the range for each of the two groups. Explain clearly what the term “peak flow” means. Describe how peak flow readings would be affected by asthma. Explain why peak flow readings would be affected by asthma. This provides evidence for P4 Task 2 Describe how a spirometer would be used safely to measure : Tidal volume Vital Capacity Oxygen consumption Use a spirometer trace to calculate the above measurements for one member of your group This provides evidence for P4 Task 3 Complete the evidence for P4 by completing the booklet This provides evidence for P4 Task 4 You must explain How the lungs are ventilated. How the tissues in the lungs assist the function. The need for a ventilation system in multi-cellular organisms This provides evidence for M3 Exam board is Pearson ALL ASSIGNMENTS I HAVE UPLOADED ARE DISTINCTION GRADED.
