structure that warms, moistens, and filters air as it enters the respitory tract; also houses the olfactory receptors for the sense of smell
roof of the mouth; partition between the oral and nasal cavities; divided into the hard and soft palate
windpipe; passageway for air from the larynx to the area of the carina, where it splits into the right and left bronchi
branched airways that lead from the trachea to the microscopic air sacs called alveoli
two spongy organs, located in the thoracic cavity enclosed by the diaphragm and rib cage, responsible for respiration
muscular partition that separates the thoracic cavity from the abdominal cavity and aids in respiration by moving up and down
thin sheets of tissue that line the respiratory passages and secrete mucus, a viscid (sticky) fluid
panting; obstructive pulmonary disease caused by a spasm of the bronchial tubes or by swelling of their mucous membrane, characterized by paroxysmal (sudden, periodic) attacks of wheezing, dyspnea, and cough
constriction of bronchi caused by spasm (involuntary contraction) of the peribronchial smooth muscle
obstructive pulmonary disease characterized by overexpansion of the alveoli with air, with destructive changes in their walls resulting in loss of lung elasticity and gas exchange (emphysan = to inflate)
chronic obstructive pulmonary disease (COPD)
permanent, destructive pulmonary disorder that is a combination of chronic bronchitis and emphysema
inflammation in the lung caused by infection from bacteria, viruses, fungi, or parasites, or resulting from aspiration of chemicals
periods of breathing cessation (10 seconds or more) that occur during sleep, often causing snoring
upper respiratory infection
infectious disease of the upper respiratory tract involving the nasal passages, pharynx, and bronchi
examination inside a body cavity with a flexible endoscope for diagnostic or treatment purposes`
use of a flexible endoscope to examine the nasal passages and the pharynx to diagnose structural abnormalities such as obstructions, growths, and cancers
techniques used during physical examination to objectively evaluate the respiratory system
to listen; physical examination method of listening to the sounds within the body with the aid of a stethoscope, such as auscultation of the chest for heart and lung sounds
physical examination method of tapping over the body to elicit vibrations and sounds to estimate the size, border, or fluid content of a cavity such as the chest
x-ray imaging of the chest to visualize the lungs; directional terms identify the path of the x-ray beam to produce the radiograph:
PA (posterior-anterior) = from back to front
AP (anterior-posterior) = from front to back
lateral = toward the side (left lateral)
CT of the thorax is used to detect lesions in the lung; CT of the head is used to visualize the structures of the nose and sinuses
x-ray imaging of the blood vessels of the lungs after the injection of contrast material
method of artificial respiration and chest compressions to move oxygenated blood to vital organs when breathing and the heart have stopped
passage of a tube into the trachea via the nose or mouth to open the airway for delivering gas mixtures to the lungs
a drugs that dissolves, or prevents the formation of, thrombi or emboli in the blood vessels
a compound in the body that is released by injured cells during allergic reactions, inflammation, and so on, causing constriction of bronchial smooth muscle and dilation of blood vessels
