Respiratory System Flashcards
How many lobes does the left lung have?
2
How many lobes does the right lung have?
3
What’s the main organ of the respiratory system?
Lungs
What’s pleura
Moist outside of the lungs
Parietal pleura
Sound of lungs
Visceral pleura
Inner layer
Pleura provides
Moisture for movement
Pleura cavity
Space between the 2 pleura
Lungs do what?
Provide the body with oxygen and removes carbon dioxide
External respiration
Breathing, exchange of air between body and outside
Internal respiration
Brining oxygen to the cells and remove carbon dioxide
Inspiration
Also known as inhalation, brings air into the mouth or nose
Air passes threw the…
Nasal cavity and paranasal sinuses
Air is warmed by…
Blood in the mucous membranes
Cilia do what
Filter out foreign bodies
Trachea
Windpipe
What connects the larynx to the right and left bronchi?
The treachea
Bronchi
Passage ways through which air enters the right and left lungs
Bronchioles
Smaller passage ways
During expiration…
Air is pushed out and into the env?
Alveoli
At the end of each bronchiole tube
Alveoli connect
To the capillaries (small blood vessels)
Where does oxygen exchange take place?
The capillaries
What is sent from the capillaries into the what
Carbon dioxide; alveoli
Oxygen is delivered where
To the body’s cells
Carbon dioxide is then…
Expelled
Muscle contractions
Enlarge the volume during inspiration and decreases volume during expiration
Major muscles
Diaphragm and intercostals muscles
The diaphragm lowers when it…
Contracts
What allows more space in the thorastic cavity?
The contraction of the diaphragm
Intercostals pulls…
The ribs upward and outward
Pharynx
throat
What’s the 3 parts of the pharynx (throat)
- ) nasopharynx
- ) oropharynx
- ) laryngopharynx
Nasopharynx
Lies above the soft palate, it contains the pharyngeal tonsils
Oropharynx
Back portion of the mouth, contains the palatine tonsils
Laryngopharynx
Bottom section
Esophagus
Passageway for food
Epiglottis
Flap that covers the larynx
Aspiration
Food goes into the larynx, helps you not choke
Larynx
Voice box
Voice box
The place where air passes to the trachea
Air goes into the
Larynx
Voice box is where
The sound of speech and singing are produced
What determines the pitch of sound
The size and thickness of the cords
Males voice box
Are thicker and longer vocal cords
Thyroid cartilage
Or Adam’s apple supports the larynx
Asthma
Obstruction of the airways
Bronchitis
Inflammation of the bronchi
Chronic obstructive pulmonary disease (COPD)
Term for any disease that causes chronic obstruction of the bronchial tubes and lungs
Epistaxis
(Nose bleed) rupture of a blood vessel
Anthracosis
Black lung, caused by coal dust in the lungs
Emphysema
Elderly smokers, build up of carbon dioxide
Lung cancer
Exposure to carcinogens
Pneumonia
Inflammation and infection in lungs
Pleurisy
Inflammation of the pleura
Hemoptysis
Chronic lung disease, tuberculosis, lung cancer, trama
Tuberculosis
Infectious disease by bacteria
Upper respiratory infection
(URI)
1 inhalation + 1 exhalation
1 respiration (complete breath)
Observe the clients
Chest movements for 1 minute
In adults and older children observe…
Chest movements
Children under 7 use…
Abdominal movement
Rate
Number of breaths per minute
Normal adult rate
12-20 breaths per minute
Respiratory rates
Decreases as a person increases I’m size
Hypoventilation
Decrease in rate
Caused by meds and lack of oxygen
Pattern
Should be regular
Quality
Seen in volume and effort
Volume
Amount of air taken in
Effort
Amount of work
Crackles or rales
Cause by fluid in the small airways
Wheezing
Sounds that are heard continuously during inspiration and expiration
Stridor
Refers to high pitched harsh sound heard during inspiration
Stridor is caused by
Obstruction of the upper air ways
Pleural run sounds
Low pitched grating or creaking sounds that occur when inflamed pleural surfaces run together during respiration
What regulates breathing unconsciously
The brain stem
Bronchial tree leads to the…
Terminal branchial
How many alveolis are there
Over 300,000
What are 3 jobs of the conducting zones
Transports
Purifies
Humidifies
What’s the 5 parts of the conducting zone?
Nose, pharynx, larynx, trachea, and epiglottis
