Which risk increases when bird trachea pressure surges?

💡 Explanation

Rupture risk increases because increased pressure will exceed tensile strength and distend the thin membranes via the mechanism of passive inflation. This leads to barotrauma; therefore, sacs rupture rather than increased lift because wing mechanics determine flow, not sacs.
