Flashcards in Chapter 7: Respiratory System Deck (128):
What are the 6 organs of the respiratory system?
What other system does the respiratory system work with?
What are the 3 parts of the respiration system?
Flow of air between outside environment and lungs
Flow of air into lungs
Brings fresh oxygen into air sacs
Flow of air out of lungs
Removes carbon dioxide from body
Exchange of oxygen and carbon dioxide in lungs
What does oxygen do in the external respiratory?
Leaves air sacs and enters blood stream
What does carbon dioxide do in the external respiratory?
Leaves blood stream and enters air sacs
Oxygen and carbon dioxide exchange at cellular level
What does oxygen do in the internal respiration?
Leaves blood stream and is delivered to tissue
Used immediately for metabolism
What does carbon dioxide do in internal respiration?
Waste product of metabolism
Leaves tisue and enters blood stream
Air enters through nares
What is the nasal cavity divided by?
Roof of mouth separates nasal cavity above from mouth below
Small hairs line opening to nasal cavity
Filter out large dirt particles before they can enter lungs
What are the walls of the nasal cavity and nasal septum made of?
What covers the walls of the nasal cavity and nasal septum?
Thick and sticky secretion of membrane that cleanses air by trapping dust and bacteria
What is the purpose of Capillaries in the mucous membrane?
Warms and humidifies air
Located within facial bones
Echo chamber for sound protection
Gives resonance to voice
Air enters trachea while food/liquid enters esophagus
What systems uses the pharynx?
What are the 3 parts of the pharynx?
Upper section by nasal cavity
Middle section by oral cavity
Lower section by larynx
Lymphatic tissue that removes pathogens in air and food
What are the 3 pairs of tonsils?
Where is the auditory tube?
Tube opens with each swallow
Equalizes air pressure between middle ear and outside atmosphere
Muscular tube between pharynx and trachea that contains vocal cords
What are the walls of the larynx?
Composed of cartilage plates
Held in place by ligaments and muscles
What forms the adam's apple?
Folds of membraneous tissue that vibrates to produce sounds as air passes through opening between folds
Flap of cartilage that sits above glottis
Covers larynx and trachea during swallowing
Carries air from larynx to main bronchi
What is the trachea composed of?
Lined with mucous membrane and cilia
Distal end of trachea divides into branches to form secondary and tertiary bronchi
Bronchiole terminates into
Bronchi continue to branch to form into
encases each alveolus
What forms the respiratory membrane?
Alveoli wall and the capillary wall
External respiration takes place across respiratory membrane
Total collection of bronchi, bronchioles, and aveoli
How many lobes does the right lung have?
How many lobes does the left lung have?
What are the 3 parts of the lung?
Pointed superior portion
Broad lower area of lung
Entry and exit point of lung
Bronchi, blood vessels, nerves
What protects the lungs?
What protects the lungs internally?
What are the 2 parts of the pleura?
Outer membrane that lines wall of chest cavity
Inner membrane that adheres to surface of lungs
Folded to form a pleural cavity
Serious fluid between 2 pleural layers reduces friction when 2 layers rub together during ventilhation
Pleura is folded to form a sac around each lung
Measures lung volumes
Pulmonary function tests
Volume of air moving in and out of lungs in a single relaxed breath
Inspiratory Reserve Volume
Volume of air that can be forcefully inhaled after a normal exhale
Expiratory Reserve Volume
Volume of air that can be forcefully exhaled after a normal exhale
Volume of air remaining in lungs after a forced exhale
Tidal Volume + Inspiratory reserve volume
Functional residual Capacity
Expiratory reserve volume + residual volume
Inspiratory reserve volume + tidal volume + expiratory reserve volume
Total Lung Capacity
Inspiratory reserve volume + tidal volume + expiratory reserve volume + residual volume
What respiratory muscles are used for inhalation?
Located between the ribs that increases negative pressure while enlarging thoracic cavity
What needs to happen in order to have an unforced exhale?
Diaphragm and intercostal muscles relax
Thoracic cavity becomes smaller
Creates positive thoracic pressure
Air flows out of lungs to equalize pressure
What is the respiratory rate dependent on?
Level of CO2 in blood
pertaining to the alveoli
pertaining to the bronchus
pertaining to a bronchiole
pertaining to the diaphragm
pertaining to the epiglottis
pertaining to the larynx
pertaining to the nose
pertaining to the pharynx
pertaining to the pleura
pertaining to the lung
pertaining to the nasal septum
pertaining to the chest
pertaining to the trachea
lack of the sense of smell
unable to obtain oxygen from inhaled air
lack of oxygen; can lead to unconsciousness and death
withdrawing fluid using suction; removing phlegm from patient's airway; inhaling food or liquid into trachea
breathing too slowly; low respiratory rate
having dilated brochi
involuntary contraction of smooth muscle in bronchial walls
abnormal breathing pattern with long periods of apnea followed by deep and rapid breathing
abnormal widening & thickening of fingers due to chronic oxygen deficiency
abnormal crackling sound during inspiration; indicates fluid or mucus in airway; also rales
blue skin caused by low oxygen in blood
difficulty producing sound
difficult or labored breathing
normal breathing and respiratory rate
cough up blood or blood-stained sputum
presence of blood in the chest cavity
ecessive carbon dioxide in the body
taking deep breaths
breathing too fast and too deep
insufficient levels of carbon dioxide in the blood
taking shallow breaths
Breathing too slow and too shallow
having insufficient amount of oxygen from inhaled air
paralysis of the muscles controlling the larynx
difficulty breathing made worse by lying flat; patient breaths better sitting up
inflammation of all the paranasal sinuses
open or unblocked
thick mucus secreted by respiratory tract
grating sound made when layers of pleura rub together during respiration
presence of pus in teh chest cavity
inflammation of the nasal cavity
rapid flow of blood from the nose
fluid discharge from the nose; runny nose
musical sound during expiration; caused by bronchial tube spasms
shortness of breath
indicates the patient is having difficulty breathing; also called dyspnea
phlegm coughed up from respiratory tract
harsh, high pitched breath sound; indicates obstruction in the airway
breathing fast; high respiratory rate
chest pain; not angina pectoris
narrowing of the trachea
