I TheoryThe activity of the respiratory centers regulate the movement ofrespiration. The respiratory centre activity in turn is influenced byafferent impulses from the lungs and various other parts of the bodyFactors whichmodifyrespirationare nervousfactors and chemicalfactors (CO2 and O2 tensions or H+ in blood or cerebrospinal fluid)There are many methods of recordingrespiratory movement: directlyrecording the change in airway pressure and electricity in diaphragmIn this experiment we adopt the methods of recording diaphragmmovement
