This chapter examines the anatomy and physiology of the respiratory system in the context of palliative care. It explains that an adult human being breathes 10,000 litres of air in 24 hours and that the primary inspiratory muscles are the diaphragm and the intercostals. The chapter discusses expiration as a passive act during tidal breathing and clarifies that neurological control of respiration depends upon modulation of two reciprocally firing neurone pools in the medulla.

Keywords: respiratory system; palliative care; inspiratory muscles; tidal breathing; diaphragm; intercostals; expiration; neurological control; neurone pools
