Discuss Boyle's law and respiratory muscle activity
What will be an ideal response?
Boyle's law states that, at any constant temperature, the pressure exerted by a gas in a closed container varies inversely with the volume of the gas—that is, as the volume of a gas increases, the pressure exerted by the gas decreases proportionately. Conversely, the pressure increases proportionately as the volume decreases. Changes in lung volume, and accordingly intra-alveolar pressure, are brought about indirectly by respiratory muscle activity. These muscles change the volume of the thoracic cavity, causing a corresponding change in lung volume because the thoracic wall and lungs are linked by the transmural pressure gradient.
