If the nerves in the exiting expiratory area were damaged, how would that affect respiration? 1) The external intercostal muscles would no longer contract during a passive exhalation. 2) The internal intercostal muscles would no longer be able to contract during a forceful exhalation. 3) The diaphragm would no longer be able to contract forcefully. 4) The person would no longer be able to voluntarily hold their breath.
