Question

how does the width of the chest change when air is inspired​

Answer 1

Answer:

HEY MATE,

HERE'S YOUR ANSWER.

=> As one inhales, the ribs move forward and outward on the body (and, in labored breathing, sometimes upward on the neck, as well). The chest circumference increases and, to an extent, so does the width. As one exhales, this movement is reversed and so are the changes in chest width and circumference.

HOPE IT HELPS YOU.
