A.
Pons region in brain
Pneumotoxic centre which can moderate the functions of the respiratory rhythm centre is present in the pons region of the brain Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiration rate.
Lungs are made up of air-filled sacs the alveoli. They do not collapse even after forceful expiration, because of :
Residual Volume
Inspiratory Reserve Volume
Tidal Volume
