22. REVISION PLAN The Respiratory systemExam QuestionsConfident of this topic Review only needed Work needed describe the mechanics of breathing at rest and the respiratory muscles involved (including the diaphragm and external intercostal muscles) explain the changes in the mechanics of breathing during physical activity including reference to additional muscles involved (sternocleidomastoid and pectoralis minor) and the active nature of expiration (internal intercostals and abdominal muscles) explain how changes in the mechanics of breathing during physical activity are regulated by the respiratory centre (both neural and chemical control) to take into account the demands of different intensities of physical activity describe the process of gaseous exchange that takes place between the alveoli and the blood and between the blood and the tissue cells. (An awareness of partial pressure is required but candidates will not be expected to provide specific respiratory pressures.)

23. CONT.. The Respiratory systemExam QuestionsConfident of this topic Review only needed Work needed explain the changes in gaseous exchange that take place between the alveoli and the blood and between the blood and the tissue cells (increased diffusion gradient and accelerated dissociation of oxy-haemoglobin) as a direct result of participation in physical activity explain the effect of altitude on the respiratory system and how it influences the performance of different intensities of physical activity; evaluate critically the impact of different types of physical activity on the respiratory system with reference to lifelong involvement in an active lifestyle (to include an awareness of asthma and smoking).
