Respiratory grunting is a sound heard at the end of which phase?

Explanation:
Grunting comes from a partial closure of the glottis during expiration, which creates a small amount of positive pressure to help keep the tiny airways open. This sound is heard at the end of expiration, as the infant finishes exhaling and is about to take the next breath. So it corresponds to expiration just before a rapid inspiration. It’s a sign of increased work of breathing and is not produced during the start of inspiration or the middle of exhalation.
