Respiratory System Flashcards
Asthenic?
Heart vertical; lung long; diaphragm low.
Thorax?
Chest.
Bones of the thorax?
Ribs
Sternum
Vertebrae.
Not clavicle
Viscera?
Organs.
Function of respiratory?
Oxygenate the blood.
Pharynx?
Throat.
Cavity behind the nose and mouth.
Larynx?
Voice box.
Laryngeal prominence?
Thyroid cartilage.
Epiglottis?
Flap of cartilage that covers the larynx when swallowing.
Bronchi?
Airways of the lungs.
Bronchioles?
Smaller bronchi.
Alveoli?
Air-filled sacs of the lungs; functional tissue of the lungs; where gas exchange takes place.
Parenchyma/interstitium?
Functional tissue of an organ.
Pleura?
Double membrane sac that sounds the lungs.
Parietal pleura?
Outer membrane
Lines the thoracic wall.
Visceral pleura?
Inner membrane
Covers the lungs.
Pleural cavity?
The space between the parietal and visceral pleura.
Mediastinum?
The space between the lungs.
Hilum?
At area of an organ where things enter and exit.
Cystic fibrosis?
Excessive secretion of mucus caused by a defective gene
The mucus obstructs the bronchi.
How is cystic fibrosis diagnosed?
Sweat test.
Prophylactic?
To prevent.
Bronchodilators?
Drugs that make the airways bigger.
Hyaline membrane disease?
Lack of surfactant in premature infants.
Surfactant?
A substance in the alveoli that allow them to stay inflated.
Radiographic appearance of underaerated lung?
Radiopague.
Croup, and radiographic appearance?
Inflammation of the upper trachea caused by a bacteria or virus
Radiographic appearance is narrowed trachea; STEEPLE SIGN
“Barking cough”
Epiglottitis, and radiographic appearance?
Inflammation of the epiglottis caused by a bacteria or virus
Radiographic appearance is rounded thickening of epiglottis. THUMB SIGN.
Pneumonia and radiographic appearance?
Inflammation of the lungs caused by a bacteria or virus
Radiographic appearance is radiopague patches.
Aspiration pneumonia?
Inflammation of the lungs caused by inhalation of gastric contents.
Respiratory syncytial virus? (RSV)
Common viral infection of the lungs in infants.
Tuberculosis? (TB)
Infection of the lungs caused by the TB bacteria.
Pulmonary mycosis?
Infection of the lungs caused by fungus.
Histoplasmosis?
Common fungal infection of the lungs in the Midwest area.
Lung abscess?
Localized collection of pus in the lung.
Chronic bronchitis?
Chronic inflammation of the bronchi caused by smoking.
*leads to COPD.
COPD? (Emphysema) and radiographic appearance.
Aveloli rupture. Air trapped in the lungs.
radiolucent.
Flattening of the domes of the diaphragm, increase in AP diameter.
BARREL CHEST.
Requires less technique.
Asthma?
Inflammation and narrowing of the airways caused by allergens.
Pneumoconiosis?
Lung disease caused by chronic inhalation of dust.
Neoplasm?
New growth.
