Question

Select INCORRECT statement about the Hering-Breuer reflex.

• A. It controls rhythm of respiration.
• B. It controls depth of respiration.
• C. It prevents the lungs from inflating to the point of bursting.
• D. It keeps the glottis open during breathing.

Hint:

The reflex works through stretch receptors in the lungs and regulates rhythm and depth of breathing.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
The Hering-Breuer reflex is a protective reflex in which stretch receptors in the lungs send signals to the respiratory centre when the lungs inflate too much.

Step 2: Check each statement
It controls the rhythm and the depth of respiration.
It prevents over inflation of the lungs.
It has no role in keeping the glottis open during breathing.

Step 3: Compare the options
The statement about keeping the glottis open is the incorrect one.

Final Answer:
The reflex does not keep the glottis open; that statement is the incorrect one. \[ \boxed{\text{(D) }\text{It keeps the glottis open during breathing.}} \]
