Cards

Term
Parenchyma
Definition
the distinguishing or specific cell of a gland or organ
Term
Pneuma
Definition
prefix that means air
Term
Pleurae
Definition
membrane enveloping lungs and lining walls of thoracic cavity.
Term
visceral pleura
Definition
membrane lying directly on the lung
Term
parietal pleura
Definition
membrane along walls of the chest and diaphragm
Term
Pleurisy
Definition
increase in the amount of pleural fluid, usually causing chest pain
Term
atelactasis
Definition
Collapsed alveoli, can be 'patchy' as after cardiac surgery, or can involve large areas of the lung
Term
Hypoxia
Definition
oxygen deficiency at the tissue level
Term
Dyspnea
Definition
difficult or labored breathing
Term
Hyperpnea
Definition
increased rate or depth of breathing, with increase in rate of pulmonary ventilation matching increase in metabolic demand.
Term
hyperventilation
Definition
increase in rate of pulmonary ventilation greater than increase in metabolic demand. Reseult: respiratory alkalosis. Interstitial alkalosis in the brain causes constriction of arterioles, resulting in mild brain ischemia, manifested as dizziness.
Term
Hypoventilation
Definition
decrease in rate of pulmoary ventilation greater than decrease in metabolic demand. This results in respiratory acidosis.
Term
Tachypnea
Definition
rapid or shallow breathing
Term
apnea
Definition
absence of breathing
Term
normocapnea
Definition
normal amounts of carbon dioxide in body
Term
hypercapnea
Definition
increased carbon dioxide in body
Term
hypocapnea
Definition
decreased carbon dioxide in body
Term
Minute ventilation
Definition
volume of air exiting the lungs in one minute. 6 L in an average adult human.
Term
Sighs
Definition
larger than normal breaths that occur automatically at regular intervals in normal subjects, possibly to counteract collapse of alveoli
Term
Obstructive pulmonary disease
Definition
disease characterized by an increase in airway resistance, primarily as a property of the conducting airways. Potential causes: aspiration due to a foreign body, buildup of mucus in airway lumen, or constriction of the airway lumen due to the contraction of smooth muscle
Term
Emphysema
Definition
disease characterized by the destruction of the alveolar walls, producing a smaller number of large alveoli
Term
Restrictive lung disease
Definition
any disorder that reduces functional residual capacity, vital capacity, or total lung capacity, thereby making the lungs difficult to inflate
Term
Lung parenchyma
Definition
restrictive disease of the lung tissue may decrease the static compliance of the lung -- mainly a property of the alveoli
Term
Pleura
Definition
buildup in the intrapleural space of either air or fluid can restrict the expansion of a vast number of alveoli
Term
Pneumothorax
Definition
buildup in the intrapleural space of AIR, causing restriction of the expansion of a vast number of alveoli
Term
Pleural effusion
Definition
buildup in the intrapleural space of FLUID, causing restriction of the expansion of a vast number of alveoli
Term
Chest wall (in terms of disease)
Definition
rigidity of this structure makes it difficult ot increase the thoracic volume
Term
Neuromuscular system (in terms of disease)
Definition
failure of this system to drive respiratory muscles appropriately decreases lung efficiency
