BIO 080 BOM TB LO2 UBAR QM - Laser Awards
Access to HE Unit: BIO 080 Body Movement (WJF678/688 G/U)Learning Outcome: LO2 (Respiratory System)To achieve level 3, address the questions correctly. Level 3 (Assessment Criterion 2.1)Q1Numerous structures make up the human respiratory system. In the diagram below (Jones 2008), the labels have been replaced with numbers. For each number, provide the name of the corresponding structure. 9101112131415Q2The respiratory system is capable of the breathing processes inhalation, relaxed exhalation and forced exhalation. They each utilise the structures in the respiratory system in different ways. The diagram below (Jones 2008) illustrates one of these processes. State which process is shown: Now, explain how this process works, relating it to structures of the respiratory system: [Q2 continued] The diagram below (Jones 2008) illustrates another one of the breathing processes. State which process is shown: Now, explain how this process works, relating it to structures of the respiratory system: [Q2 continued] The diagram below (Jones 2008) illustrates a third breathing process. State which process is shown: Now, explain how this process works, relating it to structures of the respiratory system: Level 3 (Assessment Criterion 2.2)Q3Alveoli are the smallest functional units of gas exchange in our lungs. The diagrams below (Waugh & Grant 2010) illustrate alveolar structure. Provide the names for the numbered structures. 123Explain how alveoli can fulfil the function of gas exchange, making reference to Fick’s law and to structures 1, 2 and 3 above. Level 3 (Assessment Criterion 2.3)146055588000Q4Use a spirometer to record breathing patterns in class. Then, attach spirometer traces for the same person before and after exercise to this booklet and use them to answer (a) and (b). Alternatively, use the diagram on the left (Jones 2008) with pre-recorded spirometer traces for the same person. The top trace is at rest, and the bottom trace is after exercise. Calculate the volume of air breathed per minute at rest. Show your working using tidal volume and breathing rate. [Q4 continued]Calculate the volume of air breathed per minute after exercise. Show your working, using tidal volume and breathing rate. Explain how the changes in ventilation between rest and exercise contribute to homeostasis.
