Billy is injured during a high school football game. His chest is badly bruised and he is experiencing difficulty in breathing. What might the problem be?
Billy has probably broken one or more of his ribs. Movement of the ribs changes the size of the thoracic cavity, which is an important part of breathing. When the ribs are broken, breathing can become difficult (labored) because of pain when the ribs are moved.
