What does nasopharynx oropharynx hypopharynx glottic and subglottic airway are grossly patent mean?

When it is stated that the nasopharynx, oropharynx, hypopharynx, glottic, and subglottic airway are grossly patent, it means that these areas of the airway are open and unobstructed, allowing for normal airflow. "Grossly patent" indicates that there are no visible blockages or abnormalities in these regions that would impede breathing. This assessment is typically part of a physical examination to evaluate the airways in a patient.
