'Inflation of the lungs will induce fuher distension'; this is referred to as: 
Select and explain. 
A. Hering-Breuer inflation reflex, B. Hering-Breuer deflation reflex, C. J-reflex, D. Head's paradoxical reflex
D: Head's paradoxical reflex
Answer: D: Head's paradoxical reflex 
Explanation: Head's paradoxical reflex is an example of positive feedback; distension --> fuher distension --> fuhermore distension. This occurs at bih, when the lungs are in a collapsed state and they are beginning to function thereafter. J-reflex:- Stimulation of J-receptors (pulmonary edema/congestion) --> apnea followed by rapid shallow breathing, bradycardia, hypotension.
