Chapter 13 - Respiratory System Flashcards
nasal cavity
nose, nares, cavity separated by septum
pharynx
throat, cavity behind the nasal cavities and mouth
larynx
voice organ, containing the vocal cords
trachea
windpipe
lung
two cone-shaped spongy organs consisting of alveoli, blood vessels, nerves, and elastic tissue. each is enveloped in a double-folded membrane called the pleura
parietal pleura
the serous membrane that lines the thoracic (chest) cavity
visceral pleura
membrane that covers the lungs. this membrane and the parietal membrane are close together. between them is a thin film of lubricating fluid that prevents friction when they slide against each other
bronchus (pl., bronchi)
one of the larger passages conveying air to (right or left principal lobe) and within the lungs
bronchioles
one of the subdivisions of the branched bronchial tree
alveolus (pl., alveoli)
a small saclike dilation (outpocketing) of the alveolar ducts
diaphragm
muscular partittion that separates the thoracic cavity from the abdominal cavity and aids in the process of breathing
abscess (lung)
a localized collection of pus in a cavity formed by the disintegration of tissues
anthracosis
accumulation of carbon deposits in the lung due to breathing smoke or coal dust, also known as black lung disease
ARDS
adult (acute) respiratory distress syndrome
asbestosis
lung disease caused by inhaling asbestos particles. associated with development of mesothelioma, a type of lung cancer
asphyxiation
suffocation
asthma
spasm and narrowing of bronchi, leading to bronchail airway obstruction
atelectasis
incomplete expansion of the lungs at birth, or collapse of adult lung
bradypnea
abnormally slow breathing
bronchiectasis
chronic dilation of one or more bronchi
bronchitis
inflammation of one or more bronchi
byssinosis
lung disease resulting from inhaling cotton, flax, or hemp, also know as brown lung disease
carcinoma
a malignant new growth made up of epithelial cells tending in infiltrate surround tissues and to give rise to metastases
coccidioidomycosis
a respiratory infection caused by spore inhalation of Coccidioides immitis, varying in severity from that of a common cold to symptoms resembling those of influenza; also called valley fever
