delivers oxygen to body tissues

function of the respiratory system

expel waste products returned to the lungs by the blood

function of the respiratory system

produce the airflow through the larynx that makes speech possible

connected to the nasal cavity via short ducts

para-

Fx of the sinus

to make bones of the skull lighter, help produce sound by giving resonance to the voice, to produce mucus to provide additional lubrication for the tissues of the nasal cavity

first division, posterior to the nasal cavity, continues behind the mouth

nasopharynx

allows only for the passage of air

oropharynx

visible when looking into the mouth

larynx

voice box

larynx

protected and held open by a series of nine separate cartilages

thyroid cartilage

Adam's apple

larynx

contains the vocal cords

soft palate

posterior portion of the roof of the mouth

soft palate

moves up and backward to close off the nasopharynx

soft palate

prevents food or liquid from going up into the nose

epiglottis

lidlike structure located at the base of the tongue

epiglottis

swings downward and closes off the laryngopharynx so food does not enter the trachea and the lungs

trachea

windpipe

the two branches of the trachea

bronchi

bronchioles

smallest branches of the bronchi

alveoli

air sacs

alveoli

very small grape-like clusters found at the end of each bronchiole

lungs

divided into lobes

right lung

has three lobes

right lung

superior, middle, and inferior lobes

left lung

has two lobes

left lung

superior and inferior lobes

left lung

smaller

mediastinum

located between the lungs

mediastinum

contains connective tissue and organs including the heart and its veins and arteries, the esophagus, trachea, bronchi, the thymus gland and lymph nodes

pleura

thin, moist, and slippery membrane that covers the outer surface of the lungs

pleura

lines the inner surface of the rib cage

separates the two layers of the pleura

a thin film of fluid

parietal pleura

outer laer of the pleura that lines the wall of the thoracic cavity, covers the diaphragm, and forms the sac containing each lung

parietal

relating to the walls of a cavity

visceral pleura

inner layer of pleura that surrounds each lung

visceral

pertaining to the internal organs

pleural space

pleural cavity

pleural space

airtight area between the layers of the pleural membranes containing a thin layer of fluid

pleural

pertaining to the pleura

diaphragm

the muscle that separates the thoracic cavity from the abdomen

phrenic nerve

stimulates the diaphragm and causes it to contract

phren

diaphragm

respiration

the exchange of the gases oxygen and carbon dioxide that is essential to life

external respiration

breathing

intercostal muscles

move the rib cage during breathing

inhalation

inhaling

exhalation

exhaling

diaphrgam contracts

on inhalation

on exhalation

the diaphragm relaxes

as air is inhaled into the alveoli

O2 immediately passes into the surrounding capillaries and is carried by the erythrocytes to all body cells

as air is exhaled

waste product CO2 passes from the capillaries into the airspaces of the lungs

internal respiration

the exchange of gases within the cells of all the body organs and tissues

internal respiration

oxygen passes from the bloodstream into the tissue cells

internal respiration

carbon dioxide passes from the tissue cells into the bloodstream

COPD

chronic obstructive pulmonary disease

emphysema

a decrease in the total number of alveoli, the enlargement of the remaining alveoli, the progressive destruction of the walls of the remaining alveoli

asthma

a chronic allergic disorder

upper respiratory infection

common cold

nasopharyngitis

common cold

allergic rhinitis

allergy

croup

acute respiratory syndrome in children

croup

characterized by obstruction of the larynx, hoarseness, and a barking cough

diphtheria

acute bacterial infection of the throat and upper resp tract

diphtheria

bacteria produce toxins that can damage the heart muscle and peripheral nerves

epistaxis

nosebleed

influenza

flu

influenza

acute, highly contagious viral resp. infection

pertussis

whooping cough

pertussis

contagious bacterial infection of the U.resp. tract

pertussis

recurrent bouts of a paroxysmal cough, followed by breathlessness and a noisy inspiration

paroxysmal

sudden or spasm-like

rhinorrhea

runny nose

surgical removal of all or part of a lung

pneumonectomy

surgical incision into the wall of the chest

thoracotomy

measures physiologial activity during sleep

polysomnography

bleeding from the lungs

laryngectomy

suffix meaning breathing

pnea

childhood respiratory disease characterized by a barking cough

croup
