Question

Quizplus · Accepted Answer

The expansion of the lungs during inhalation is due to the increase in volume of the thoracic cavity, which leads to a decrease in pressure within the lungs, causing air to flow in. The diaphragm and other respiratory muscles contract to enlarge the thoracic cavity, allowing for the expansion of the lungs. The upward movement of the shoulder girdle does not play a significant role in lung expansion. Lung tissue does not actively stretch but rather passively expands and contracts with changes in pressure and volume. The rebound from exhalation is not the primary mechanism for lung expansion during inhalation.
