Ventilation and the exchange of gases in the lungs. The mechanism of breathing. 0.4 Explain the role of ventilation in terms of maintaining diffusion gradients. Explain the mechanism of breathing in of the action of the diaphragm muscle and the antagonistic action of the external and internal intercostal muscles and the pressure changes which they cause in the thoracic cavity. Learning activities: use balloon lungs in a jar, or get students to construct a lung model, to show breathing is due to changes in pressure due to changes in thoracic volume teacher explanation of the mechanism of breathing exam questions on the mechanism of breathing students given data relating to pulmonary ventilation rate and one other measure exam questions. Skills developed by learning activities: MS 2.2 – students could be given values of pulmonary ventilation rate and one other measure, requiring them to change the subject of the equation: PVR = tidal volume × breathing rate Students could undertake the HBI3T ISA Q from 2010 Specimen assessment material: AS 2 (set 1) – Q4.1–4.2 Past exam paper material: BIOL1 Jan 2013 – Q1 BIOL1 Jan 2012 – Q2 BIOL1 June 2010 – Q2 June 2012 – Q6 BIOL 4 Jan 2011 – Q6a and 6b
