What is the Result of the Inflation Reflex

Question

What is the result of the inflation reflex?
A)An increase in the duration of inspirations
B)An increase in the duration of expirations
C)A decrease in the duration of inspirations
D)A decrease in the duration of expirations
E)An increase in the duration of inspirations and a decrease in the duration of expirations

Accepted Answer

The inflation reflex, also known as the Hering-Breuer reflex, is activated by stretch receptors in the lungs. When these receptors detect high lung volumes, they send signals to the respiratory center in the brainstem to inhibit inspiratory neurons and stimulate expiratory neurons. This results in a decrease in the duration of inspirations and helps prevent overinflation of the lungs. Therefore, the best choice is C, as it describes a decrease in the duration of inspirations.
