What does the inflation reflex do?
The Hering–Breuer reflex (also called the inflation reflex) is triggered to prevent over-inflation of the lungs.

Which of the following is involved in inflation reflex?
Cardiac and respiratory branches of the vagus nerve: The vagus nerve is the neural pathway for stretch receptor regulation of breathing. The Hering–Breuer reflex (also called the inflation reflex) is triggered to prevent over-inflation of the lungs.
What do you mean by Hering-Breuer reflex?
: any of several reflexes that control inflation and deflation of the lungs especially : reflex inhibition of inspiration triggered by pulmonary muscle spindles upon expansion of the lungs and mediated by the vagus nerve.

Which is a structural or functional characteristic of the inflation reflex?
Which is a structural or functional characteristic of the inflation reflex? It involves receptors in the carotid and aortic sinuses. It stimulates the inspiratory centers of the VRG. It inhibits respiratory muscles via the respiratory rhythmicity centers.
Which muscles are used to breathe?

Which muscles are used to breathe in normally?
The diaphragm, a dome-shaped sheet of muscle that separates the chest cavity from the abdomen, is the most important muscle used for breathing in (called inhalation or inspiration). The diaphragm is attached to the base of the sternum, the lower parts of the rib cage, and the spine.

(And one thing that can destroy it, after a few day’s delay, is a massive overdose of Tylenol.) It’s the second largest organ in the body, second only to the skin.
