Respiratory System Flashcards
Adenoids
Lymphatic tissue in the Nasopharynx; pharyngeal tonsils.
Alveolus / Alveoli
Air sack in the lung 
Apex of the lung
Tip or uppermost portion of the lung. Apical means pertaining to or located at the Apex.
Base of the lung
Lower portion of the lung. Basilar means located at or in the base 
Bronchioles
Smallest branches of the bronchi. 
Bronchus / Bronchi
Branch of the trachea, that is a passageway into the lungs; bronchial tube 
Carbon dioxide (CO2)
Gas produced by body cells when oxygen and carbon atoms from food combine; exhale through the lungs 
Cilia
Thin hairs attached to the mucus membrane epithelium lining the respiratory tract. They clear bacteria and foreign substances from the lung. 
Diaphragm
Muscle separating the chest and abdomen. Contracts to pull air into the lungs and relaxes to push air out 
Epiglottis
Lid-like piece of cartilage that covers the larynx, preventing food from entering the larynx and trachea during swallowing 
Exhalation
Breathing out;expiration
Glottis
Slit-like opening to the larynx
Hilum of the lung
The Hilum is what connects your lungs to their supporting structures and where pulmonary vessels enter an exit your lungs. Hilar means pertaining to (at) the Hilum 
Inhalation
Breathing in; inspiration
Larynx
Voice box
Lobe
Division of a lung 
Mediastinum
Region between the lungs and the chest cavity, it contains the trachea, heart, lymph nodes, major blood vessels, esophagus, and bronchial tubes 
Nares
Openings through the nose carrying air into the nasal cavities; nostrils 
Oxygen (O2)
Gas that makes up 21% of the air that we breathe. It passes into the bloodstream at the lungs and travels to all the body cells.

Palatine tonsil
One of a pair of almond shaped masses of lymphatic tissue in the oropharynx (palatine means pertaining to the roof of the mouth )
Paranasal sinus
One of the air cavities in the bones near the nose
Parietal pleura
Outer layer of pleura line closer to the ribs and chest wall 
Pharynx
Throat, including the nasopharynx, oropharynx, and laryngopharynx
Pleura
Double layered membrane surrounding each lung 
Pleural cavity
Space between the layers of the pleura
Pulmonary parenchyma
Essential parts of the lung responsible for respiration ; bronchioles and alveoli
Respiration
Exchange of gases, (oxygen and carbon dioxide) at the lung capillaries, (external respiration or breathing), and at the tissue capillaries (internal respiration. )
Trachea
Windpipe
Visceral pleura
Inner layer of plural line closer to the lung tissue

Auscultation
Listening to sounds within the body 
Percussion 
Tapping on a surface to determine the difference in the density of the underlying structure 
Pleural rub
Scratchy sound produced by plural surfaces, rubbing against each other. (Also known as a friction rub)
Rales
crackling, bubbling, or rattling sounds heard on auscultation (during inhalation) when there is fluid in the alveoli. 
Rhonchi (singular: rhonchus)
Loud rumbling sounds heard on auscultation of bronchi obstructed by sputum.
Sputum
Material expelled from the bronchi lungs or upper respiratory tract by spitting. A mixture of saliva and mucus (phlegm)
Purulent
Containing pus
Stridor
An abnormal, high-pitched respiratory sound produced by irregular airflow in a narrowed airway. This condition indicates upper airway obstruction. 
Wheezes
Continuous, high-pitched whistling sounds produced during breathing 
Croup
Acute viral infection of infants and children with obstruction of the larynx , accompanied by barking cough and stridor
Diphtheria
Acute infection of the throat and upper respiratory tract caused by the diphtheria bacterium (corynebacterium)
