Respiratory System3

Respiratory System

The oral cavity refers to the? mouth
Two structures located at the posterior portion of the oral cavity are the? Palatine tonsils
The tonsils are? lymph tissue
Lymph tissue is part of your? immune system
The nasal cavities refer to the? nose
The two meati of the nasal cavities are called? nostrils or external nares.
The hairs found lining the nasal cavities act as? screening devices.
The nasal cavities are separated by the? nasal septum
The nasal cavities house the sense of smell referred to as the? olfactory sense
The nasal cavities are lined with? mucous membranes.
Mucous membranes produce? mucus
The pharynx is AKA? throat
The oropharynx refers to the ? oral cavity (mouth) and pharynx (throat)
Nasopharyngeal means? pertaining to the nasal cavity (nose) and pharynx (throat)
The adenoids are located in the? nasopharynx
The adenoids are? lymph tissue
Lymph tissue is part of your? immune system
The nasopharynx also houses two ducts that lead to the middle ears called ? Eustachian tubes.
The function of the Eustachian tubes is to? equalize pressure between the middle ear and the outside environment in order to prevent prevent tympanorrhexis.
The larynx is AKA? "vocal cords" or "voice box."
The larynx connects the? pharynx with the trachea
Larngopharynx(hypopharynx) refers to the? larynx and pharynx
The larynx is supported by pieces of? cartilage
These pieces of cartilage are called? 1. the thyroid cartilage. 2. the epiglottis 3. the cricoid cartilage
The largest piece of cartilage is the? thyroid cartilage AKA "Adam's apple."
The epiglottis is the? "lid over the larynx"
The epiglottis is designed to? open when we breathe and close when we swallow.
The glottis is the? space between the larynx (vocal cords)
The trachea is AKA the? "windpipe"
The bronchi are the? two main airway branches that bifurcate of the trachea.
These two main branches are called the? right primary bronchus and the left primary bronchus.
On entering the lungs the primary bronchi divide to form smaller bronchi called the? secondary (lobar) bronchi.
The secondary or lobar bronchi continue to branch forming even smaller bronchi called? tertiary (segmental) bronchi.
Tertiary or segmental bronchi divide into smaller branches called? bronchioles.
Bronchioles finally branch into even smaller tubes called? terminal bronchioles.
The terminal bronchioles subdivide into microscopic branches called? respiratory bronchioles.
These respiratory bronchioles subdivide into? alveolar ducts.
The alveolar ducts house alveoli in the? alveolar sacs
The alveolar sacs house the? alveoli.
The continuous branching of the trachea is referred to as the? "bronchial tree."
It is estimated that the average number of alveoli in a human is? 30 million.
every alveolus is surrounded by? capillaries
The alveoli is the where? respiration occurs
The gases that are exchanged are? oxygen(O2) carbon dioxide (CO2)
Respiration is the? exchange of gases
Respiration involves two processes and the first process is? 1.External respiration which is the - exchange of gases that occurs between the lungs and blood.
Respiration involves two processes and the second process is? 2.Internal respiration which is- the exchange of gases that occurs between the blood and body cells.
Every cell of the body is surrounded by? capillaries
The actual exchange of the respiratory gases between the lungs, blood, and cells occurs by? diffusion
Diffusion means? the process in which the particles in fluid or gas move from an area of higher concentration to an area of lower concentration.
The cavity where the respiratory organs are found is the? thoracic cavity
The lungs are divided into sections called? lobes
The right lung has? 3 lobes (right upper lobe, right medial lobe, right lower lobe.
The left lung has? 2 lobes (left upper lobe, left lower lobe).
The primary bronchi are lined with small hair-like structures called? cilia.
The purpose of the cilia is to? catch foreign particles that are inhaled during inspiration.
As the cilia becomes saturated from the inhaled particles the mucous membranes that line the respiratory tract will produce? mucus
The purpose of the mucus is to? trap the foreign particles.
When enough mucus is produced the nervous system will trigger the? cough reflex
when the cough flex is trigger then persons first choice is to? 1. cough the mucus up and spit it out.
when the cough flex is trigger then persons has second choice? 2. cough the mucus up and swallow it.
A productive cough refers to a? cough where sputum is produced.
A non-productive cough refers to a? dry cough (no sputum) such as croup (bark-like cough).
Antitussive refers to a? cough suppressant.
The act of coughing up mucus is called? expectoration (expectorate).
The mucus expectorated is called? sputum or phlegm.
Normal sputum (phlegm) appears? clear or white.
Mucopurulent refers to? mucus and pus
Hemoptysis means? expectorating blood
Yellow,green, or pungent sputum (phlegm) can indicate? infection.
C + S stands for? culture and sensitivity
A C + S is performed to grow antigens and determine the best antibiotic to? treat the infection
Two membranous layers surround each lung called? pleurae
The purpose of the pleurae is to? protect the lungs from the ribs.
The outermost pleural layer is called the? parietal pleura
The innermost pleural is called the? visceral pleura
Between the parietal and visceral is a space called the? pleural cavity (space)
The pleural cavity(space) contains? pleural fluid (lubricating fluid) to prevent friction between the parietal and visceral pleurae during ventilation.
Ventilation refers to? breathing
PFT stands for? pulmonary function test
Incentive spirometry (IS) is a? test to measure the ability to self-ventilation.
Tidal volume (TV)is? the amount of air volume that can be inhaled beyond a normal resting inspiration.
Inspiratory reserve volume (IRV)? the volume of air that can be inhaled beyond a normal resting inspiration.
Expiratory reserve volume (ERV)? the volume of air that can be exhaled beyond a normal resting expiration.
The process of moving air in and out of the lungs is called? ventilation (breathing)
The two phases of ventilation are? inhalation (inspiration) and exhalation (expiration)
The muscles primarily responsible for ventilation are the? 1. Diaphragm 2. Internal and external intercostals
Intercostal means? space between the ribs.
Ventilation is controlled by is controlled by the respiratory center located in the? medullar oblongata.
A ventilator refers to? a device that pushes air in and out of the lungs.
Intubation (intubate)? the process of inserting a tube.
Intubation usually refers to an? endotracheal tube (ET)
The instrument used to insert an endotracheal (ET) is called an? laryngoscope
Ambu bag refers to? bag that is used to ventilate an apnic patient
Apnic means? no breathing
ABGs means? arterial blood gases
Oxygen saturation(SaO2)? the amount of oxygen (O2) that has combined with (saturated) hemoglobin.
Percentage of carbon dioxide (PCO2) means? the amount or percentage of carbon dioxide (CO2) that has combined with hemoglobin.
A nebulizer is a? device that delivers vaporized medicine (vaporizer)
CXR stands for? chest x-ray.
NPPV stands for? noninvasive positive pressure ventilation (a respiratory Tx)
Oximetry refers to? the process of measuring oxygen.
Rales refer to? crackling sounds heard during auscultation.
Auscultation means? listening with a stethoscope
Rhonci refers to? wheezing
Stridor refers to? a high pitched sound indicative of airway obstruction
RT (IT) stands for? respiratory therapy (inhalation therapy)
C-PAP stands for? continuous positive airway pressure
C-PAP is a treatment for? obstructive sleep apnea (OSA)
