Question

Quizplus · Accepted Answer

During inhalation, the primary muscle involved is the diaphragm (D), which contracts and moves downward to increase the thoracic cavity volume. The external intercostals (A) also play a significant role by elevating the ribs, further expanding the thoracic cavity. In forced inhalation, accessory muscles such as the sternocleidomastoid (F) are recruited to elevate the sternum and clavicles, enhancing lung expansion.
