Final answer:
Supraglottic swelling refers to swelling above the level of the glottis, while subglottic swelling refers to swelling below the level of the glottis. Both types of swelling can cause difficulty breathing and may require medical intervention.
Step-by-step explanation:
The question asks about supraglottic swelling and subglottic swelling. The glottis is the opening to the larynx. Supraglottic swelling refers to swelling above the level of the glottis, while subglottic swelling refers to swelling below the level of the glottis.
For example, if there is inflammation or swelling in the area above the glottis, it would be considered supraglottic swelling. On the other hand, if there is inflammation or swelling in the area below the glottis, it would be considered subglottic swelling. Both types of swelling can cause difficulty breathing and may require medical intervention.
