Cards

Term
structures of the lung, from largest to smallest
Definition
trachea, bronchi, terminal bronchioles, respiratory bronchioles, alveolar ducts, and alveolar sacs
Term
acinus
Definition
respiratory bronchioles, alveolar ducts, and alveolar sacs
Term
respiratory bronchioles
Definition
conduct air and serve in respiration
Term
respiratory zone
Definition
alveolar ducts and alveolar sacs, their main function is gas exchange.
Term
mucociliary escalator
Definition
Particles are caught in a raft of mucus, which is swept upward by beating cilia on the lung epithelial cells
Term
Type II pneumocytes
Definition
make surfactant
Term
Ventilation
Definition
the bringing in and distribution of a volume of air
Term
Perfusion
Definition
circulation of blood in the lung
Term
Most pneumonias are
Definition
bacterial
Term
Bronchopneumonia
Definition
This type of pneumonia is very commonly acquired by hospitalized patients
Term
Staphylococcus. Strep and fungi can also be a cause.
Definition
Common organism that cases bronchopneumonia
Term
Only a few organisms can cause lobar pneumonia.
Definition
Streptococcus pneumoniae (which is the same as Pneumococcus and is the most common cause), Klebsiella (also called Friedlander's bacillus), and Legionella pneumophila.
Term
Infection with Klebsiella is associated with...
Definition
alcoholism
Term
consolidation
Definition
The filling of airspaces during pneumonia
Term
Double pneumonia
Definition
two lobes are involved
Term
walking pneumonia
Definition
the patient is well enough that he or she is not confined to bed.
Term
If pneumonia is associated with pain,
Definition
there is most likely also infection of the pleural membranes covering the lung. The lung itself has no pain receptors
Term
Lobar pneumonia
Definition
characterized by a widespread, even distribution throughout one or more lobes of the lung.
Term
interstitial pneumonia
Definition
the air spaces are not filled. The walls of the alveoli become inflamed, but the inflammation does not spill out into the air spaces
Term
Community acquired pneumonia's
Definition
Lobar and interstitial pneumonia's
Term
Viruses that can cause pneumonia include:
Definition
Influenza (especially influenza A)
Parainfluenza
Respiratory syncytial virus
Adenovirus
Varicella (chickenpox)
Herpesvirus hominis
Cytomegalovirus
Measles virus
Term
Organization or carnification:
Definition
the lung becomes solid, inelastic and meat-like due to scarring. Like cardiac muscle, lung tissue cannot regenerate.
Term
Empyema
Definition
accumulation of pus in the pleural cavity. Often requires surgical drainage.
Term
Bacteremic
Definition
infection can spread outside the lung, leading to endocarditis, meningitis, septic arthritis, etc.
Term
Staph often causes
Definition
multiple abscesses that are not putrid
Term
Abscesses that form from aspiration of vomit
Definition
caused by anaerobic organisms from the mouth and tend to be putrid and foul-smelling.
Term
Cytomegalovirus (CMV)
Definition
also present in healthy individuals. New infections can be of concern during pregnancy, since this virus can cross the placenta and involve the fetus.
Term
Mycobacterium avium intracellulare (MAI)
Definition
not usually present in healthy people
Term
Mycobacterium tuberculosis
Definition
not usually present.
Term
Toxoplasma
Definition
can involve lung, but is usually more of a problem in the brain. Also can affect fetus if a woman is infected for the first time while pregnant.
Term
bronchiectasis,
Definition
bronchi become dilated and have a "sac-like" quality. Occurs due to a manifestation of severe and persistent lung infection.
Term
Ghon foci
Definition
The localized, chronic inflammatory lesions of primary tuberculosis
Term
Ghon complex
Definition
The infection may spread to regional lymph nodes. The infected nodes and the Ghon foci together form
Term
miliary TB
Definition
Sometimes in children or in immunocompromised individuals, the first infection with TB will become spread throughout the lung or even throughout the body via the blood
Term
caseous necrosis,
Definition
The type of necrosis associated with TB
Term
Cryptococcus
Definition
a yeast that can cause meningitis even in healthy people, but it more commonly infects those who are immunocompromised.
Term
Some other TB-like diseases caused by fungi
Definition
histoplasmosis, Coccidioides.
Term
Chronic bronchitis
Definition
Chronic bronchitis is characterized by excessive, chronic mucus production and cough in the absence of infection, and it usually results from smoking.
Term
Emphysema
Definition
the internal architecture of the lung is destroyed. There is a departitioning of the lung as the walls of the acini are ruptured and destroyed.
Term
pink puffers
Definition
characteristically suffer from emphysema. They overbreathe because they feel that they are not getting enough air and are often thin and wasted, since a lot of energy is expended trying to breathe.
Term
blue bloaters
Definition
They are bloated because they are edematous due to right heart failure (called cor pulmonale - right heart failure due to lung disease). Blue bloaters characteristically suffer from chronic bronchitis.
Term
bullae
Definition
In emphysema, big air-filled spaces in the lung
Term
Pulmonary edema
Definition
fluid in the airspaces) can result from heart disease or from toxins (noncardiogenic pulmonary edema).
Term
Asthma
Definition
It is a generally reversible obstruction of the lung marked by bronchospasm and increased secretions
Term
Lung parenchymal disease
Definition
diffuse interstitial fibrosis or scarring; diffuse infiltration without scarring; edema)
Term
Adult respiratory distress syndrome (ARDS) (also called diffuse alveolar damage):
Definition
The capillaries become leaky, and the air spaces fill with exudate. The exudate and damaged cells may form a thick band called a hyaline membrane that lines the air spaces.
Term
hyaline membrane
Definition
The exudate and damaged cells may form a thick band
Term
Neonatal RDS (also called hyaline membrane disease)
Definition
a similar syndrome seen in premature newborns, particularly those delivered by C-section, who have lungs that are still immature. In this case, the capillary damage and leak result from lack of sufficient surfactant to keep the air spaces open.
Term
Bronchiolitis obliterans organizing pneumonia (BOOP):
Definition
It is often a catch-all term for lung conditions that are not pneumonias. BOOP is marked by inflammation and obstruction of bronchi with pneumonia and fibrosis. The fibrosis (scarring) is reversible up to a point. Formation of fibrotic tissue can be suppressed with steroids.
Term
Pneumoconiosis
Definition
chronic inflammation of the lung due to inhalation of dusts, such as silica, asbestos, and coal dust
Term
Wegener's granulomatosis
Definition
can affect both the lungs and the kidney's
which is often (not always) marked by anti-neutrophil cytoplasmic antibodies (ANCA).
Term
Goodpasture's syndrome
Definition
can effect both the lungs and the kidney's. Caused by antibodies directed against the glomerular basement membrane
Term
Oat cell carcinoma (also called small cell carcinoma)
Definition
) is rarer but very aggressive and invariably fatal. Oat cell carcinoma is seldom treated surgically, because the tumor has almost always spread by the time it is discovered. Therefore, chemotherapy is the treatment of choice
Term
Pancoast tumors
Definition
arise in the apex of the upper lobes and may lead to head, neck, and arm symptoms.
Term
paraneoplastic syndromes
Definition
clubbing of the fingers (which occurs for unknown reasons and may also be associated with other conditions), or various conditions that arise from abnormal production of hormones by the tumor cells (such as enlargement of the breasts in males)
Term
Oat cell carcinomas are
Definition
notorious for producing hormones inappropriately.
Term
hamartoma
Definition
The only benign tumor of note in the lung. which is a cartilaginous tumor that looks like a kernel of popcorn on x-ray
Term
mesothelioma
Definition
malignant tumors in the lung.
