Q

trachea
passageway for air that extends from pharynx and larynx down to main bronchi
27
bronchus
tube that enters one of the lungs; left and right
28
bronchioles
narrowest branches of bronchi, end in a small group of air sacs
29
alveoli
small group of air sacs at the end of a bronchiole; 150 million in each lung
30
pulmonary capillaries
capillaries from the pulmonary blood vessels that encase the alveolus
31
respiratory membrane
walls of alveoli and capillaries. exchange of oxygen and carbon dioxide between the air in the alveolus and blood in the capillaries takes place across this
32
lungs
total collection of bronchi, bronchioles, and alveoli
33
pleura
double membrane that protects the lungs
34
parietal pleura
outer membrane around lungs which also lines the wall of the chest cavity
35
visceral pleura
inner membrane around lungs which sticks to the surface of the lungs
36
pleural cavity
sac around each lung
37
serous fluid
fluid between two layers of the pleura that reduces friction when the two layers rub together
38
lobes
divisions of the lungs. right lung contains 3 (right upper, right middle, and right lower) and left lung contains 2 (left upper and left lower)
39
apex
pointed superior portion of the lung
40
base
broader lower portion of the lung
41
hilum
area along the medial border of lungs where entry of structures like the bronchi, pulmonary blood vessels, and nerves occur
42
mediastinum
area between the lungs. contains heart, aorta, esophagus, thymus gland, and trachea
43
respiratory therapists
conduct pulmonary function tests to help determine the functioning level of the respiratory system
44
pulmonary function test
measuring the volume of air flowing in and out of the lungs to determine lung capacity
45
diaphragm
separates the abdomen from the thoracic cavity that contracts to decrease pressure in the thoracic cavity, allowing air to flow into the lungs to equalize the pressure
46
intercostal muscles
between the ribs; raise the ribcage to enlarge the thoracic cavity to make it easier for air to flow into the lungs
47
vital signs
VS; respiration, pulse, temperature, skin color, blood pressure, reaction of pupils
48
anosmia
lack of sense of smell
49

77

malignant tumor originating in the bronchi
86
adult respiratory distress syndrome
acute respiratory failure in adults characterized by tachypnea, dyspnea, cyanosis, tachycardia, and hypoxemia
87
anthracosis
pneumoconiosis that develops from collection of coal dust in the lung. aka black lung or miners lung
88
atelectasis

progressive, chronic, and usually irreversible group of conditions where the lungs have decreased capacity
90
cystic fibrosis
hereditary condition causing exocrine glands to malfunction and produce thick mucus that causes severe congestion within lungs and digestive system
91
