    The lecture Emphysema: Pathogenesis A by Carlo Raj, MD is from the course Obstructive Lung Disease.

    Included Quiz Questions

    1. Centrilobular emphysema is associated with the destruction of all parts of the acinus
    2. Cigarette smoking is an important risk factor
    3. Release of proteolytic enzymes destroys the alveoli
    4. Loss of tissue causes loss of radial traction upon expiration and subsequent air trapping
    5. Loss of air bronchioles usually in the upper and middle lobe
    1. Septal loss
    2. Dilatation of the acinus
    3. Decreased recoil
    4. Rupture of the acinus
    5. Compression of the affected acinus
    1. Neutrophils
    2. Lymphocytes
    3. Macrophages
    4. Clara type 1 pneumocytes
    5. Clara type 2 pneumocytes
    1. Alpha 1 antitrypsin
    2. Protease
    3. Surfactant
    4. Mucopolysaccharides

    1. Purse the lips and breath out
    2. Breathing into a plastic bag
    3. Coughing up sputum to expectorate the mucus
    4. Opening the windows to breathe in fresh air
    5. Sleeping with 3 pillows under the head
    1. It provides resistance, allowing an increase in pressure at the alveoli to prevent the collapse of it
    2. It provides more oxygen to the lung
    3. It helps maintain the respiratory drive
    4. It prevents the progression of the disease
    5. It helps exchange of gases in the alveoli
