“Collapsed” alveoli of lungs (decrease in size/deflated) due to surfactant deficiency
Atelectasis
“Ectasis” - collapse
COPD (3)
Bronchiectasis
Emphysema
Chronic bronchitis
BQ: disease assoc with “Barrel chest appearance”
COPD* (boards)
- Emphysema
Collapsed bronchi (dilatation of respiratory tract) usually due to CYSTIC FIBROSIS!!(inc mucus prod:loss of cilia: cant breathe)
Bronchiectasis
“Pink puffer”

“Trapped air”
Emphysema
Most common chronic disease of the lungs
Emphysema
Increase in size of the air spaces (nawawalan ng elasticity ung alveoli)
Emphysema
“Barrel chest appearance”
Emphysema
Choices sa boards: COPD!
Inflammation of bronchi due to Inhalation of pollutants (smoking and pneumoconiosis)
Chronic bronchitis

Enlargement of right ventricles
Cor pulmonale
Bronchial epithelium to squamous change
Assoc with asbestosis

BQ: Most common death causing cancer in MALE(or female 2018)
Lung cancer
Most common death causing cancer in women (old statistics)
Breast cancer
Most common cancer in male

Doc for gerd
Omeprazole (PPI)
Treatment for GERD (2)
Omeprazole H2 blockers (ranitidine/cimetidine)
Metaplastic change assoc with GERD
Barret’s esophagus
Decrease function of heart; resulting to decrease blood flow to organs
Heart failure
Most common type of CHF
Left CHF
Causes of left CHF
Hypertension
Rheumatic fever
MI
Larger type of circulation: Systemic or pulmonary?
Systemic - larger
Vessels involved in Pulmonary circulation
2 only:
Pulmo artery and vein
(the rest sa systemic na)
What ventricle supplies the systemic circulation
Left ventricle
Ventricle that is involved in pulmonary circulation
Right ventricle
Fat + Calcium =
Plaque
Sudden attack of severe shortness of breath during the night
Paroxysmal nocturnal dyspnea
Shortness of breath while lying
Two-pillow orthopnea (positional dyspnea)
Paroxysmal nocturnal dyspnea Two-pillow orthopnea Tachypnea Pleural effusion Pulmonary edema - Are characteristic of what CHF?
Left CHF - Lungs affected
Body compensation to heart failure:
- Increases heart function ➡️ Hypertrophy of Left ventricle ➡️ Congestion
- Fluid retention = ⬆️BF = ⬆️BS
- Hypertrophy
What happens if there’s congestion in the left ventricle:
- Decrease blood systemic circulation
- Back flow of blood in the lungs (kaya hirap sila huminga)
- R-CHF
BQ: Pigment carried by Heart failure cells
Hemosiderin
Dust cells: eat yung rbc sa lungs = end product: hemosiderin
Most common cause of R-CHF
