Factors that Regulate Ventilation Rate

Stimulus: stretch of lung

Receptor: stretch receptor in lung

Effect: inhibits repsiration
Stimulus: increase P_CO2

Receptor: peripheral chemoreceptors and medullary respiratory center

Effect: increased P_CO2 causes decrease pH via carbonic anhydrase: the decreased pH is what actually sensed
Stimulus: decrease pH

Receptor: peripheral chemoreceptors and medullary respiratory center

Effect: increases respiratory rate
Stimulus: decrease P_O2

Receptor: peripheral chemoreceptors

Effect: increases respiratory rate
Stimulus: chemical irritation

Receptor: irritant receptor in lung

Effect: coughing and/or bronchoconstriction
