All are true about Hering-Breuer inflation reflex Except?

A
Functions as a protective mechanism.
B
Functions as a protective mechanism.
C
Involves inhibition of the inspiratory center.
D
Protects against under inflation of the lungs.
High-Yield Explanation
The shoening of inspiration produced by vagal afferent activity is mediated by slowly adapting stretch receptors, as are the Hering-Breuer reflexes. The Hering-Breuer inflation reflex is an increase in the duration of expiration produced by steady lung inflation, and the Hering-Breuer deflation reflex is a decrease in the duration of expiration produced by marked deflation of the lung. Because the rapidly adapting receptors are stimulated by chemicals such as histamine, they have been called irritant receptors. Ref : Barrett K.E., Barman S.M., Boitano S., Brooks H.L. (2012).
