OF THE RESPIRATORY SYSTEM MALFUNCTIONS OF THE RESPIRATORY SYSTEM

BRONCHITIS Inflammation of the linings of the bronchial tubes Air passages become swollen and clogged with mucus Causes coughing and breathing difficulty Caused by bacteria or virus

BRONCHITIS

ASTHMA A severe allergic reaction Constriction of the bronchioles makes breathing difficult

ASTHMA

EMPHYSEMA Walls of the alveoli break down Less respiratory surface Shortness of breath

PNEUMONIA Disease caused by bacteria or viruses Alveoli fill with fluid Prevents gas exchange

LUNG CANCER Tumors form in the lungs as a result of irregular cell growth
