To air
Respiratory system consists of:
Nose, pharynx, larynx, trachea, bronchi, lungs
Respiratory system’s primary function
Supply oxygen for tissues and take away carbon dioxide
Respiration
R
Consists of external and internal processes
External respiration
Lungs are ventilated and oxygen and carbon dioxide are exchanged between the air in the lungs and blood in the capillaries of the alveoli
Internal respiration
Oxygen and carbon dioxide are exchanged between blood in tissue capillaries and cells of the body
Nose
Serves as an air passageway that warms and moistens air, and its vi,ia help filter foreign material
Pharynx
Passageway for air and food, 5 inches long from base of skull to esophagus
Larynx
Produces vocal sounds; short tense cords make high sounds, long relaxed cords make low sounds; enlarged upper end of trachea
Bronchi
Provides passageway for air to and from lungs; divide into right and left bronchus
Lungs
Brings air into contact with blood so oxygen and carbon dioxide can be exchanged
Anterior nares
External entrance of nose
Nostrils
Four Paranasal Sinuses
Frontal, maxillary, ethmoidal, sphenoidal
Frontal sinuses
Located above eyebrows
Maxillary sinuses
Cheeks on either side of nose
Ethmoidal sinuses
Either side of bridge of nose close to the eyes
Sphenoidal sinuses
Behind ethmoid sinuses close to ears
3 Portions of Pharynx
Nasopharynx, oropharynx, laryngopharynx
Nasopharynx
Located behind the nose (contains adenoids or pharyngeal tonsils)
Oropharynx
Located behind mouth (contains faucial or palatine tonsils and lingual tonsils)
Laryngopharynx
Located behind larynx
Tonsils
3 pairs of lymphoid tissues
Adenoids or pharyngeal tonsils, faucial or palatine tonsils, and lingual tonsils
Function of tonsils?
Filter bacteria from lymph in head and neck region
Cavity of larynx contains
Ventricular folds and vocal folds
Ventricular folds
False vocal cords
Vocal folds
True vocal cords
3 Regions of Larynx Cavity
Vestibule, ventricle, entrance to glottis
Glottis
Narrow slit at opening between true vocal cords
3 Unpaired Cartilages of Larynx
Thyroid, cricoid, epiglottis
3 Paired Cartilages of Larynx
Arytenoid, cuneiform, corniculate
Thyroid cartilage
Largest cartilage, forms Adam’s apple
Epiglottis
Covers entrance of larynx, acts as a lid to prevent aspiration of food
Cricoid cartilage
Lowermost cartilage
Trachea
Air passageway from pharynx and larynx to bronchi; 1 in. wide and 4.5 in. long; reinforced in front and sides by cartilage rings
Bronchial tree
Smaller bronchi, bronchioles, alveolar ducts; ends in alveoli
Hilium
Depression on lung where bronchus enters
alveoli
Tiny air sacs supporting capillaries from pulmonary vessels
Lungs
Conical shaped spongy organs lying on both sides of the heart in the pleural cavity
Pleura
Serous membrane composed of several layers
Pleural cavity
Space between parietal and visceral pleura that contains serous fluid
Diaphragm
Musculomembranous wall that separates thoracic cavity from abdominal cavity
Mediastinum
Central portion of thoracic cavity between lungs that contains the heart and other structures
Base
Broad inferior surface of lung that rests on diaphragm
Apex
Pointed upper margin of lung
Lobes
Right lung has 3, left lung has 2
Cardiac depression
Indentation in left lung for placement of heart
Main function of lungs
Bring air into contact with blood so oxygen and carbon dioxide can be exchanged in alveoli
Tidal volume
TV
Amount of air in a single inspiration and expiration: avg 500 mL
Expiratory reserve volume
ERV
Amount of air that can be forcibly expired after normal respiration; aka supplemental air, 1000-1200 mL
Inspiration reserve volume
IRV
Amount of air that can be forcibly inspired after a normal inspiration, 3600 mL
Residual volume
RV
Amount of air remaining in lungs after max expiration, 1500 mL
Vital capacity
VC
Volume of air that can be exhaled after max inhalation
Functional residual capacity
Volume of air that stays in lungs after normal expiration
Total lung capacity
TLC
Max volume of air in lungs after max inspiration
Vital signs
Essential elements for determining state of health
Temperature, pulse, respiration, blood pressure
What regulates respiration?
Medulla oblongata and pons
Newborn respiratory rate
30-80 per min
1st year respiratory rate
20-40 per min
5th year respiratory rate
20-25 per min
15th year respiratory rate
15-20 per min
Adult respiratory rate
12-20 per min
Acid-fast bacilli
AFB
Test on sputum to detect tuberculosis
Antistreptolysin O
ASO
Test on blood serum to detect strep
Arterial blood gases
ABGs Measures acidity (pH) and levels of oxygen and carbon dioxide in blood
Bronchoscopy
Visual examination of larynx, trachea, and bronchi via bronchoscope
Culture, sputum
Examination of sputum to determine presence of pathogenic microorganisms
Culture, throat
Test that identifies presence of pathogenic microorganisms in the throat
Laryngoscopy
Visual examination of larynx via laryngoscope
Pulmonary function test
Series of tests performed to determine diffusion of oxygen carbon dioxide across cell membrane in lungs
Rhinoscopy
Visual examination of nasal passages
