MDA109 Chapter 7 Respiratory System

anorexia loss of appetite
diffuse spreading out
septum wall dividing 2 cavities (ex: the nasal septum separates the 2 nostrils)
serous membrane thin layer of tissue that covers internal body cavities, the cells of which secrete a fluid that keeps membrane moist (AKA serosa)
olfacotry neurons receptors for sense of smell
mediastinum space between right and left lungs
pleura a serous membrane,covers the lobes of the lungs and folds over to line the walls of the thoracic cavity
parietal pleura membrane that lines the thoracic cavity
visceral pleura membrane lying closest to the lungs
pleural cavity space between parietal and visceral pleura
inspiration drawing air into the lungs
expiration air leaving the lungs
pulmonary ventilation breathing
external respiraiton exchange of oxygen and carbon dioxide between alveoli and the blood in the pulmonary capillaries
transport of respiratory gases when blood (aided by cardiovascular syatem) transports CO2 to lungs and O2 to body cells
internal respiration exchange of O2 and CO2 between body cells and blood in systemic capillaries
sept/o septum
bronchi/o bronchus
bronch/o bronchus
bronchiol/o bronchiole
alveol/o alveolus, air sac

Pulmonology medical specialty concerned with disorders of the respiratory system
Pulmonologist physician who treats disorders of the respiratpry system
Chronic obstructive respiratory disease (COPD) included respiratory disorders that produce a chrinic partial obstruction of the air passages (3 major ones: asthma, chronic bronchitis, emphysema)
asthma spasma in the bronchial passages
chronic bronchitis inflammation of the bronchi
emphysema decreased elasticity of the alveoli
pleural effusions any abnormal fluid inthe pleural cavity (the space between visceral and parietal pleura)
auscultation listening to the sounds made by the organs of the body using a stethoscope
percussion gentle tapping on the chest and listening to the resultant sounds to determine size, posotion, or consistency of underlying structures
transudate noninflammatory fluid, resembles serum
tuberculosis (TB) communicable disease caused by a bacteria
pnemonia any inflammatory disease of the lungs, may be casued by bacteria, virus, or fungi
consolidation lung tissue loses it's spongy texture and becomes swollen and engorged
cystic fibrosis hereditary disorder of endocrine glands casues body to secrete extremely thick (viscous) mucus
viscous thick
normal flora fungus that normally resides in people
acute respiratory distress syndrome (ARDS) a condition in which thelungs no longer work effectively, threatning the life of the patient
systemic infection infection affecting the entire body
sepsis blood infection
edema when the alveoli fill with blood
bronchogenic carcinoma (AKA primary pulmonary cancer) lung cancer usu asoc with smoking
acidosis excessive acidity of body fluids
anosmia absence of sense of smell
-sphyxia pulse
atelectasis collapsed or airless state of the lung
atel- incomplete, imperfect
-ectasis dilation, expansion
cheyne-Stokes respiration repeated breathing pattern: deep, then shallow, then not at all
compliance ease with which lung can be stretched
coryza upperrespiratory infection(URI), (AKA, a head cold)
crackle abnormal respiratory sound
croup common childhood condition involving inflammation of the larynx, trachea, bronchial passages and sometimes lungs
epistaxis nosebleed, nasal hemorrhage
finger clubbing enlargement of the terminal phalanges of fingers and toes, assoc with pulmonary disease
hyp/ox/emia emia: blood conditionhyp: under, below, deficientox: oxygendeficiency of oxygen in the blood
hypoxia deficiency of blood in the tissues
pertussis acute infectious disease characterized by a whooping cough (AKA whooping cough)
pleurisy inflammationf the pleural membrane characterized by stabbing pain worsened by coughing or deep breathing
coni: dust
embol plug
-us condition, structure
rhonchus abnormal breath sound heard on auscultation
stridor high-pitched, harsh, adventitious breath sound caused by spasm or swelling of larynx or an obstruction in upper airway
wheeze whistling or sighing sound heard on auscultation results form narrowing of lumen of the respirsatory passageway
Mantoux test test for TB exposure, past or present, or vaccine
oximetry noninvasive method of monitoring th percentage of hemoglobin saturated with oxygen (AKA pulse oximetry, pulse ox)
polysomnography test of sleep cycles and stages using continuous recording of various things
pulmonary function tests multiple tests used to evaluate ability of the lungs to take in and expel air and perform gas exchange
spirometry measurement of ventilatory ability by asessing lung capacity and flow
arterial blood gas (ABG) test that measures partial pressure of oxygen, carbondioxide, pH, andbicarbonate level of an arterial blood sample
sputum culture microbial test used to identify those disease causing organisms of the lower respiratory tract, esp those causing pnemonia
sweat test measeures amount of salt (sodium chloride) in sweat
aerosol therapy lung treatment using various techniques to deliver medication in mist form
lavage irrigating or washing out of an organ with a stream of water or other fluid
postural drainage positioning a patient so that gravity aids in the drainage of secretions
