Q.174. Which of the following is mainly a protective mechanism for preventing excess lung inflation rather than an important component in the regulation of respiration?
(1) Haldane effect
(2) Hering-Breuer reflex
(3) Cyanosis
(4) Bohr effect

Dear student

Please refer the solution below for the said query


The correct option is (2).

There are stretch receptors in the lungs that relay to the medulla of brain. When the lungs are over inflated, these receptors send a proper feedback stopping the further inspiration. This is called Hering-Breuer reflex. 



Hope this information clears your doubt about the topic.
