A physical therapy student compares inspiration and expiration during quiet breathing. Which combination correctly contrasts the active or passive nature, the muscular contributions, and the pressure changes in each phase?

Inspiration is active and requires contraction of the diaphragm and external intercostals, increasing thoracic volume and lowering intra-alveolar pressure below atmospheric pressure; quiet expiration is passive and driven by elastic recoil of the thoracic cage and lung tissue, raising intra-alveolar pressure above atmospheric pressure Inspiration is passive and driven by elastic recoil; quiet expiration is active and requires contraction of the internal intercostals Both inspiration and expiration result in the same pressure change in the same direction across the cycle Both inspiration and expiration are active processes that require muscle contraction during quiet breathing
