Which statement describes the role of convexity?

Explanation:
Convexity uses an outward-curving barrier to press gently around the stoma. This pressure helps create a secure seal at the skin edge, especially when the stoma is flush, recessed, or there are skin folds. By pushing the peristomal skin toward the stoma, convexity reduces gaps where stool could leak and helps direct output into the opening, protecting the surrounding skin. It isn’t about increasing airflow, changing the barrier’s stiffness, or curing infection.
