Transcript
Control of Respiration
• Respiratory centre as an integrator of inputs from chemoreceptors, other receptors and higher centres
• Exercise
• Chemoreceptors: Peripheral (respond to changes in O2, CO2 and pH
• Inputs from other receptors
• Outputs to respiratory muscles and muscles of upper airway
Regulation of Ventilation
Inputs
• higher centres
• chemoreceptors
• “visual receptors”
Brain stem
Integrator
neural control
Respiratory centres
Outputs
• muscles of respiration rate & depth
• smooth mucle airways
• muscels upper airways (esp to during inspiration)
