Bronchus	one of the two branches formed by division of the trachea
Hilum	notch or depression where the bronchus, blood vessels, and nerves enter the lung
Bronchiole	small air-conducting tube containing a smooth muscle layer but little or no cartilage
Surfactant	substance in the fluid lining the alveoli that prevents their collapse
Exhalation	phase of pulmonary ventilation in which air is expelled from the alveoli
Inhalation	phase of pulmonary ventilation in which the diaphragm contracts

Bicarbonate ion	important blood buffer produced from carbon dioxide
Hemoglobin	substance that carries most of the oxygen in the blood
Oxygen	gas that is more concentrated in the blood than in metabolically active tissues
Hydrogen ion	an ion that renders blood more acidic
Hypoxia	lower than normal concentration of oxygen in tissues
Dyspnea	symptom of difficult or labored breathing
Hydrogen ion	substance that acts directly on the central chemoreceptors to stimulate breathing
Hypocapnia	the change in carbon dioxide concentration resulting from hyperventilation
Hypoxemia	a lower than normal blood concentration of oxygen
Brain stem	location of the central chemoreceptors
Hypercapnia	an increase in the blood carbon dioxide concentration
Aortic arch	location of a peripheral chemoreceptor
Acute coryza	technical name for the common cold, based on the discharge of fluid from the nose
Effusion	collection of fluid, as may occur in the pleural space
Lobar pneumonia	a bacterial or viral infection that affects an entire lung at once
TB	infectious lung disease characterized by the presence of small lung lesions
Hay fever	an allergic reaction that affects the upper respiratory tract and eyes
Asthma	an allergic reaction that affects the bronchial tubes
Croup	a condition in young children in which the airways are constricted as a result of a viral infection
Emphysema	destruction of the alveoli of dthe lungs often related to heavy smoking
Tracheotomy	an operation to insert a metal or plastic tube into the trachea to serve as an airway for ventilation
Bronchoscope	instrument used to inspect the bronchi and their branches
Pleurisy	inflammation of the serous membrane covering the lungs
Hemothorax	accumulation of blood in the pleural space
Atelectasis	scientific term for a collapsed lung
Chronic bronchitis	a type of COPD in which the airways are continually inflamed
SIDS	scientific term for "crib death"
External exchange of gases	Carbon dioxide will diffuse out of blood during the phase of respiration
Deviated septum	structural defect of the partition in the nose
Cheyne-Stokes respiration	rhythmic abnormality in breathing that is seen in critically ill patients
Hay Fever	allergic rhinitis is the medical term
An increase in blood carbon dioxide levels would result in what?	more hydrogen ions in the blood
Upper respiratory infections:	Croup, RSV, acute coryza
Surfactant	substance that reduces surface tension in the alveoli
Residual volume	amount of air that is always in the lungs, even after a maximal expiration
Pneumothorax	presence of air in the pleural space
Glottis	space between the vocal cords
Pleurisy	inflammation of the membranes around the lungs
Partial pressure	term that is used for the pressure of each gas in a mixture of gases
Each heme region of a hemoglobin molecule contains an inorganic element called?	Iron
Pneumonia	certain diplococci, staphylococci, chlamydias, and viruses may caouse an inflammation of the lungs
organism that causes tuberculosis	Mycobacterium tuberculosis
nerve that innervates the diaphragm	Phrenic nerve
Hypercapnia results in greater blood acidity.	Most oxygen in the blood is carried bound to hemoglobin
The wall of an alveolus is made of simple squamous epithelium	Durning internal exchange of gases, oxygen moves down its concentration gradient out of blood.
Chemoreceptors	receptors that detect changes in blood gas concentrations
The alveoli become filled with exudate in patients suffering from pneumonia.	Inhalation alway involves muscle contraction
Polyp	tumor resulting from chronic sinusitis that obstructs air movement
Hyperventilation results in a decrease of carbon dioxide in the blood.	(blank)
