Respiratory system
B2.8 The role of the components in performing the functions of the respiratory system:
• components of the respiratory system:
o trachea
o lungs
o bronchi
o bronchioles
o alveoli
o pleural membranes
o ribs
o intercostal muscles
o diaphragm
• functions of relevant components within the respiratory system:
o inspiration and expiration, including pressure changes within the chest cavity
o gas exchange
B2.9 The role of the alveoli as a specialised exchange surface in the process of gas exchange:
• how adaptation of the alveoli maximise the rate of diffusion:
o large surface area to volume ratio
o good blood supply
o short diffusion distance
o moisture levels
o body temperature
B2.10 The development, impact and management of chronic obstructive pulmonary disease (COPD):
• causes of the disease
• impact on systems within the body and on physical and mental health
• how common treatments relieve symptoms:
o inhalers
o steroids
o lifestyle changes to promote self-care and better health
o pulmonary rehabilitation
o surgery
