RESPIRATORY DISORDERS Bronchitis Asthma Emphysema Lung cancer

CHRONIC BRONCHITIS Chronic – long term - usually caused by an irritant – ie smoking - cilia become damaged and can’t clear debris

EMPHYSEMA

EMPHYSEMA CAUSE: usually from many years of smoking Effects are permanent and incurable

ASTHMA Asthma is a chronic respiratory disorder Bronchi and bronchioles are affected – bronchiole muscles tighten, mucus is produced – breathing is difficult

ASTHMA ATTACK Generally it is thought that asthma is somewhat inherited TRIGGERS – include pollen, dust, smoke, pets, exercise

Normal Lung vs. Cancerous Lung

LUNG CANCER Cancerous tumors take over healthy lung tissue – making breathing difficult

Lung Cancer Linked with cigarette smoking Metastases = Cancer tumors can spread to other parts of the body
