Respiratory System Flashcards
Respiration
exchange of gases between the body and air
Nose
external portion composed of cartilage and bone and covered in skin
Nasal Cavity
divided into left and right chambers by a dividing wall called the septum
Paranasal Sinus
- hollow area or cavities within the skull that communicates with the nasal cavity
Pharynx
- airway that connects the mouth and nose to the larynx
- throat
Nasopharynx
- behind the nose
- contains the adenoids
Oropharynx
- behind the mouth
- contains palatine tonsils
Laryngopharynx
behind the larynx
Larynx
- connects the pharynx to the trachea
- contains vocal cords, produces sound when air passes through
- voice box
Trachea
- extends into the chest and serves as a passageway for air to the bronchi (connects to lung)
- windpipe
Bronchi
- trachea branches into two tubes called the bronchi
- each branch leads to a separate lung
Bronchioles
-smallest branches of the bronchi
Lungs
- two cone- shaped, spongy organs consisting of the alveoli, blood vessels, elastic tissue, and nerves
- Left lung has 2 lobes
- Right lung has 3 lobes
Pleura
double-folded membrane that surrounds the lungs
Pleural Space
small space between the pleural membranes
Inspection
visual examination of the external surface of the body as well as of its movements and posture
Palpation
process of examining to detect evidence of disease or abnormalities in the various organs
Auscultation
process of listening for sounds within the body, usually to the sounds of the thoracic or abdominal viscera, to detect some abnormal condition, or to detect fetal heart sounds
Percussion
use of the fingertips to tap the body lightly but sharply to determine the position, size, and consistency of an underlying structure and the presence of fluid or pus in a cavity
Apnea
temporary cessation of breathing
Bradypnea

Cough
- forceful and sometimes violent expiratory effort preceded by a preliminary inspiration
- due to irritation of the airways or infection

expelling air forcibly through the nose and mouth by spasmodic contraction of muscles of expiration due to irritation of nasal mucosa
Stridor
- harsh sound
- high pitched and resembling the blowing of wind, due to the obstruction of air passages
Tachypnea
abnormal rapidity of breathing
Wheeze
whistling sound or sighing sound resulting from the narrowing of the lumen of a respiratory passageway

inflammation of the respiratory mucous membranes; common cold
Croup
- childhood disease characterized by a barking cough, hoarseness, tachypnea, inspiratory stridor, and laryngeal spasm

inflammation of the pharynx, usually resulting in sore throat
Rhinitis
- inflammation of the mucous membranes of the nose
- coryza
Sinusitis
inflammation of a sinus, especially a paranasal sinus
Tonsillitis
inflammation of the palatine tonsils; tonsils are enlarged and red with yellowish exudate
Asthma
paroxysmal dyspnea accompanied by wheezing; caused by a spams of the bronchial tubes or by swelling of their mucus membrane
Bronchiectasis
chronic dilation of a bronchus or bronchi, with secondary infection that usually involves the lower portion of the lung
Bronchitis
inflammation of the mucous membrane of the bronchial tubes
Acute Bronchitis
causes: viral infection, bacterial infection, and airborne irritants
Chronic Bronchitis
primarily associated with cigarette smoking or exposure to pollution
Bronchogenic Carcinoma
- malignant lung tumor that originates in the bronchi
- lung cancer
