tonsill/o

trache/o
trachea
uvul/o
uvula
structure that warms, moistens, and filters air as it enters the respiratory tract
nose
air-filled spaces in the skull that open into the nasal cavity
sinuses
roof of the mouth
palate
bony anterior portion of the palate
hard palate
muscular posterior portion of the palate
soft palate
throat
pharynx
part of the pharynx directly behind the nasal passage
nasopharynx
central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis
oropharynx
lower part of the pharynx
laryngopharynx
oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion
tonsils
lymphatic tissue on the back of the pharynx behind the nose
adenoid
small projection hanging from the back middle edge of the soft palate
uvula
voice box
larynx
opening between the vocal cords in the larynx
glottis
a lid-like structure that covers the larynx during swallowing to prevent food from entering the airway
epiglottis
windpipe
trachea
branches airways that lead from the trachea to the microscopic air sacs
bronchial tree
two primary airways branching from the area of the carina into the lungs
right and left bronchus
progressively smaller tubular branches to the airways
bronchioles
thin-walled, microscopic air sacs that exchange gases
alveoli
two spongy organs in the thoracic cavity enclosed by the diaphragm and rib cage
lungs
subdivisions of the lung
lobes
membranes enclosing the lung and lining the thoracic cavity
pleura
potential space between the visceral and parietal layers of the pleura
pleura cavity
muscular partition that separates the thoracic cavity from the abdominal cavity and that moves upward and downward to aid in respiration
diaphragm
partition that separates the thorax into two compartments and that encloses the heart, esophagus, trachea, and thymus gland
mediastinum
thin sheets of tissue that line respiratory passages and secrete mucus, a viscid fluid
mucous membranes
hair-like processes from the surface of epithelial cells, such as those of the bronchi, to move mucous cell secretions upward
cilia
functional tissues of any organ, such as the tissues of the bronchioles, alveoli, ducts and sacs, that perform respiration
parenchyma
normal breathing
eupnea
slow breathing
bradypnea
fast breathing
tachypnea
shallow breathing
hypopnea
difficulty breathing
dyspnea
inability to breathe
apnea
ability to breathe only in an upright position
orthopnea
pattern of breathing characterized by gradual increase of depth and, sometimes in rate to a maximum level followed by decrease resulting in apnea
Cheyne-Stokes respiration
popping sounds heard on auscultation of the lung when air enters diseases airways and alveoli
crackles, rales
