Question

Quizplus · Accepted Answer

The external obliques, internal obliques, and rectus abdominis are all abdominal muscles that, when contracted, can compress the abdominal cavity and push the diaphragm upwards, aiding in exhalation. The external intercostals, in contrast, are involved in elevating the ribs during inhalation, not in pushing up on the diaphragm.
