Bronchial Obstruction in Lungs - Medical Illustration & Explanation #3880401 (License: Personal Use)

This medical illustration depicts the human respiratory system, focusing on the trachea bifurcating into the left and right main bronchi, which further branch into smaller bronchioles within the pink lung tissue. The magnified inset reveals a cross-section of a bronchus severely constricted by a dark red mucus plug, illustrating pathologies such as asthma, COPD, or bronchitis. The image uses color contrast to emphasize airflow restriction and tissue inflammation.

Used in healthcare websites, patient education portals, and medical textbooks to explain airway obstruction mechanisms. Targets users searching for symptoms, causes, or visual aids related to respiratory diseases like asthma, bronchitis, or cystic fibrosis.
