Respiratory System

mucous membrane moist tissue layer lining hollow organs and cavities of the body that open to the environment
serous membrane thin layer of tissue that covers internal body cavities and secretes a fluid that keeps the membrane moist
pharynx throat. muscular tube that serves as a passageway for food and air
three sections of pharynx nasopharynx, oropharynx and laryngopharynx
nasopharynx posterior to the nose
oropharynx posterior to the mouth
laryngopharynx superior to the larynx
adenoids pharyngeal tonsils. Collection of lymphoid tissue in the nasopharynx
Palatine tonsils aka tonsils. located in oropharynx. Protect the opening to the respiratory tract from microscopic organisms that may attempt entry by this route.
larynx voice box. contain the structures that make vocal sounds possible.. Short passage that joins the pharynx with the trachea
The right lung has ____ lobes 3
The left lung has _____ lobes 2
mediastinum space between the right lung and the left lung
Pleura serous membrane. Covers the lobes of the lungs and folds over to line the walls of the thoracic cavity.
Visceral pleura membrane the lies closest to the lungs
Parietal pleura membrane that lies closes to the thoracic cavity
Pleural cavity space between the visceral pleura and the parietal pleura. Contains lubricating fluid
Diaphragm assists in changing the volume of the thoracic cavity to produce the needed pressure differential for ventilation
pulmonary ventilation breathing. Large involuntary action that moves air into and out of lungs in response to changes in blood O2 and Co2 levels and nervous stimulation of the diaphragm and intercostal muscles
external respiration exchange of O2 and CO2 between the alveoli and the blood in the pulmonary capillaries
transport of respiratory gases occurs when blood, aided by the cardiovascular system transports CO2 to the lungs and O2 to the body cells.
internal respiration exchange of O2 and CO2 between body cells and the blood in systemic capillaries
pneumo air, lung
pulmon lung
anthrac coal, coal dust
atel incomplete, imperfect
coni dust
orht straight
phren diaphragm
spir breathe
-capnia carbon dioxide
-osmia smell
-phonia voice
-ptysis spitting
Chronic obstructive pulmonary disease (COPD) includes respiratory disorders that produce a chronic partial obstruction of the air passages
Three major disorders of COPD asthma, chronic bronchitis and emphysema
Asthma produces spasms in the bronchial passages that may be sudden and violent and lead to dyspnea.
status asthmaticus life threatening. medication doesnt work
emphysema decreased elasticity of alveoli. Able to dilate but cant constrict
pleural effusion abnormal fluid in the cavity
transudate serum with less protein in pleural cavity. Heart failure and liver disorders
Exudate high in protein + blood. Tumor, infection, inflammation
pneumothroax results in collapsed lung
pneumonia inflamed lungs
pneumocystis pneumonia associated with AIDS
acute respiratory disease syndrome (ARDS) lungs dont function well. Alveoli filled with fluid
Hyaline membrane disease (HMD) aka infant respiratory distress syndrome (IRDS). Preterm infants/diabetic mothers
acidosis excessive acidity of body fluids
ansomia no sense of smell
atelectasis collapsed/airless lung
coryz inflammation of membranes of nose
Cheyne Stokes respiration fluctuation of breath. pattern. Deep then shallow then deep
Croup pediatric. inflammation of larynx, trachea, bronchial passges
epistaxis nosebleed
pertussis whopping cough
pleurisy inflammation of pleural membrane
pneumoconiosis disease caused by inhaling dust
pulmonary embolism blockage in artery of lung
rhoncus abnormal breath sound
stridor high pitched breath sound, spasm of larynx
wheeze narrowing of lumen
antral lavage irrigation/washing of sinuses
oximetry monitors percentage of hemoglobin saturated with oxygen
polysomnograph test of sleep cycle
postural drainage positioning patient so that gravity aids in drainage of lungs
pulmonary function tests variety of tests used to evaluate respiratory function
mantoux test for TB. skin test
CTPA images of pulmonary arteries
antitussives blocks coughing
