pollutants |
substances that makes an environment not clear and impure |
|
6 connected elements of respiratory tract |
Nose, pharynx, larynx, trachea, bronchi & bronchioles, and alveoli |
|
Respiration |
transport of O2 from outside air to tissue cells and transport of CO2 in opposite direction |
|
Four components of Respiration |
1. Ventilation 2. Pulmonary exchange of gases 3. Gas transport 4. Peripheral gas exchange |
|
ventilation |
movement of air and its gases into and out of lungs |
|
pulmonary exchange of gases |
between air in alveoli and pulmonary capilaries |
|
gas transport |
from pulmonary capillaries through arterial system to peripheral capillaries in tissues and the transport of gases back to the lung capillaries through venous system |
|
peripheral gas exchange |
between tissue capillaries and tissue cells for use in cellular metabolism |
|
5 functions of Respiratory System |
1. Exchange of gases 2. Regulation of blood pH 3. Protection 4. Voice production 5. Olfaction |
|
spirometer |
instrument used to measure respiratory volumes |
|
Functions of nose |
1. passageway for air 2. air cleanser 3. air moisturizer 4. air warmer 5. sense of smell |
|
common cold |
viral upper respiratory infection |
|
rhinitis |
inflammation of nasal mucosa, also called coryza |
|
Allergic rhinits |
swelling of mucous membranes of the nose, pharynx, and sinuses with clear watery discharge |
|
sinusitis |
infection of paranasal sinuses, often following a cold |
|
Epistaxis |
nosebleed |
|
Cautery |
agent or device used to burn or scar a tissue |
|
concha |
shell-shaped bone on lateral wall of ansal cavity |
|
decongestant |
agent that reduces the swelling and fluid in the nose and sinuses |
|
meatus |
passage or channel; also used to denote the external opening of a passage |
|
mucopurulent |
mixture of pus and mucus |
|
naris |
nostril |
|
sinus |
cavity or hollow space in a bone or other tissue |
|
pharynx |
muscular funnel that receives air from nasal cavity and food and drink from oral cavity |
|
division of pharynx |
1. nasopharynx 2. oropharynx 3. laryngopharyx |
|
nasopharynx |
located back of nose, above soft palate and uvula. lined with a mucous membrane that includes goblet cells: produce mucus |
|
oropharynx |
located below soft palate and above epiglottis. contains two sets of tonsils |
|
laryngopharynx |
located below tip of epiglottis, pathway to esophagus. only food and drink passes through |
|
snoring |
disorder of pharynx |
|
obstructive sleep apnea |
obstruction by soft tissues at back of the nose and mouth causes frequent episodes of gasping for breath followed by complete cessation of breathing |
|
pharyngitis |
acute or chronic infection involving pharynx, tonsils and uvula |
|
tonsillitis |
infection of tonsils by a virus |
|
nasopharyngeal carcinoma |
rare form of cancer that occurs mostly in males |
|
hypoxia |
below normal levels of oxygen in body as a whole or a region of the body |
|
functions of larynx |
1. thyroid and cricoid cartilages maintain an open passage for movement of air to and from trachea 2. epiglottis and vestibular folds prevent food and drink from entering the larynx 3. vocal cords are source of sound production |
|
Laryngitis |
inflammation of mucosal lining of larynx, producing hoarseness and sometimes progressing to loss of voice |
|
epilottitis |
inflammation of epiglottis |
|
croup |
group of viral diseases in children aged 3 months - 5 years. Inflammation and obstruction of upper airway |
|
papillomas |
benign tumors of larynx result from overuse |
|
caricinoma |
production of a persistent hoarseness |
|
Right lung has three lobes (superior, middle, and inferior) |
Left lung has two lobes (superior and inferior) |
|
fissure |
deep furrow or cleft |
|
hilum |
site where nerves and blood vessels enter and leave an organ |
|
mediastinum |
area between lungs containing the heart, aorta, venae cavae, esophagus and trachea |
|
visceral pleura |
serous membrane covering each lung |
|
pleural cavity |
space between visceral and parietal pleurae |
|
functions of pleurae |
1. reduce friction 2. assist in inspiration 3. separation |
|
inflation |
process of expanding with air |
|
parietal |
pertaining to outer layer of pericardium and other body cavities |
|
pericardium |
tissue covering the heart |
|
pleura |
membrane covering the lungs and lining the ribs in the thoracic cavity
|
|
surfactant |
a protein and fat compound that creates surface tension to hold lung alveolar walls apart |
|
symptoms and signs of respiratory disorders |
1. coughing 2. dyspnea 3. cyanosis 4. changes in rate of breathing 5. sneezing |
|
acute bronchitis |
viral or bacterial, production of excess mucus with some obstruction of airflow |
|
chronic bronchitis |
due to cigarette smoking or repeated episodes of acute bronchitis |
|
bronchiolitis |
inflammation of small airway bronchioles |
|
pulmonary emphysema |
disease of bronchioles and alveoli. Airways become enlarged and septa between the alveoli are destroyed, forming large sacs. |
|
